High-Efficiency, 10 A, High-Voltage Direct Charger Datasheet Revision 3.2 14-Feb-2022 CFR0011-120-00 1 of 51 © 2022 Renesas Electronics General Description DA9318L/M is a direct charger using a high-efficiency current doubler with integrated Analog to Digital Converter (ADC) for system monitoring. The device is especially optimized to handle high charging currents and at the same time ensure the safety of the battery and the system. It operates together with a main charger, which handles the pre-charge and constant voltage charging duties. The current doubling is achieved with a high-efficiency capacitive divider that provides an output voltage of VIN/2, which allows the use of standard Type-C™ cables for charging currents up to 6 A. The peak efficiency of DA9318L/M is 98 %. Available as two variants, the DA9318L provides a maximum 8 A charging current and 35 W of charging power, whereas DA9318M provides 10 A output current and 44 W of charging power. An integrated reverse protection feature blocks current flow in both directions while the device is not operational. Additionally, the battery is protected by DA9318L/M by six hardware based safety functions for any over- or under-voltage condition. All safety triggered events lead to an automatic shutdown and are reported via interrupt to the system. DA9318L/M features an 8-bit ADC for input and output current and voltage, and junction temperature monitoring which ensures safety during direct charging. For software supervision a programmable watchdog timer, and for battery overload protection a safety timer, are included. An I2C compatible 2-wire interface is provided for the device control. The DA9318L/M is available in a small WLCSP 3.62 mm × 3.78 mm package. Key Features ■ 8 A output current (DA9318L) ■ 10 A output current (DA9318M) ■ 98 % efficiency at 2 A ■ 5 % current sense accuracy (DA9318L) ■ 10 % current sense accuracy (DA9318M) ■ Reverse and forward current protection in IDLE mode ■ I2C compatible 2-wire interface ■ 8-bit ADC to measure voltage and current at the input and output as well as junction temperature ■ Safety timer and watchdog ■ Automatic shutdown in fault condition ■ Travel adaptor detection ■ No inductors ■ WLCSP package: 3.62 mm × 3.78 mm

9.1 Current Doubler
The current doubler operates with a fixed duty cycle. Under no-load condition, the output voltage is half of the input voltage. When a current IOUT is drawn at the VOUT node and the current doubler is switching at an fSW frequency, the output voltage is determined as: OUTIEQRINV OUTV *2 − = REQ is a function of the sum of all resistances in the input/output power path (including the power device’s on-resistance and the PCB routing resistance) as well as the switching frequency, CFLY and PCB parasitics. The dual phase interleaved operation ensures an almost constant input current, thereby highly improving the application design against noise. The voltage ripple at VOUT can be first order approximated as the voltage drop due to the discharge of the CFLY capacitor in half of the period at an fSW switching frequency, plus the discharge voltage of the output VOUT capacitor during a typical 5 ns short dead time for phase switch.
High-Efficiency, 10 A, High-Voltage Direct Charger Datasheet Revision 3.2 14-Feb-2022 CFR0011-120-00 24 of 51 © 2022 Renesas Electronics Selecting a good CFLY capacitor is a key factor for a well performing current doubler. Increasing the switching frequency and the VOUT capacitors to compensate for the DC bias degradation of CFLY may both result in a worse efficiency. For a list of suggested external components see Table 12.
9.1.1 Reverse Current Protection
RCP is enabled whenever DA9318L/M is not in the ACTIVE mode. The current doubler blocks current flow from IN to OUT and from OUT to IN. In this mode, the C1P and C2P terminals are floating.
9.1.2 Switching Frequency
In normal conditions the switching frequency of the current doubler is static and it is defined by the CP_FREQ register bits.
9.1.3 Start-Up
The current doubler is capable of starting up when VIN is within the accepted range defined by VIN2OUT_MIN and VIN2OUT_MAX. If VIN is not within the accepted range during start-up, the start-up is aborted and an event is triggered (E_VIN2OUT_MIN or E_VIN2OUT_MAX). Resuming normal operation after a start-up fault requires that VIN is within the accepted range and the event is cleared.
9.1.4 Current Limit
The maximum continuous output current of the current doubler is IOUT_MAX. In addition, individual switching FETs are protected with cycle-by-cycle peak current limit of ILIM_PK. The configurable integrated current limit is aimed to protect DA9318L/M power stages and the external components from excessive current. When hitting the current limit, a timer is started. If the current limit is exceeded for longer than tDEGLITCH_ILIM_PK, the current doubler is disabled and an event E_ILIM_OC_CRIT is triggered.
9.1.5 Input-to-Output Voltage Protection
DA9318L/M features an input-to-output voltage protection described in section 9.3.3. The protection is used to automatically disable the current doubler when the input-to-output voltage ratio is out of the accepted range defined by VIN2OUT_MIN and VIN2OUT_MAX. When the either of these thresholds is crossed during current doubler operation an event, E_VIN2OUT_MIN or E_VIN2OUT_MAX, is triggered and the current doubler is automatically disabled.
9.2 Travel Adaptor Detection
The detection of a travel adaptor insertion is made based on rising VIN voltage. The detection of a travel adaptor removal is made based on falling VIN voltage. When VIN exceeds VTHR_RISE the travel adaptor status bit S_VIN_ADP_DET is asserted and the associated event (E_VIN_ADP_DET) is triggered. The travel adaptor status bit and the current doubler enable are de-asserted when VIN falls below VTHR_RISE.
9.3 Voltage Protection
Figure 11 illustrates the voltage protection, including the VIN and VBAT voltage protection levels. All voltage protection functions have an event associated with them, which is triggered whenever the comparator trips.

9.3.1 Input Voltage Protection
Input voltage (VIN) protection is used for detecting the presence of an input supply and for disabling the current doubler when VIN rises too high. Note that the current doubler is only operational when VIN is within the range defined by VIN2OUT_MIN and VIN2OUT_MAX. VIN over-voltage conditions longer than tDEGLITCH_OV will disable the current doubler by disabling CP_EN and will trigger the event E_VIN_OV. Resuming normal operation after the over-voltage event is triggered requires that the event is cleared and that the current doubler is re-enabled either by writing CP_EN or by asserting the nCPEN signal. Under-voltage conditions longer than tDEGLITCH_UV will disable the current doubler by disabling CP_EN and trigger the event E_VIN_UV. Resuming normal operation after the under-voltage event is triggered requires that the event is cleared and that the current doubler is re-enabled either by writing CP_EN or by asserting the nCPEN signal. The adaptor detection is made by comparing VIN to a threshold VTHR_RISE. If VIN is above VTHR_RISE, a supply is assumed to be detected. When VIN falls under the VTHR_RISE – VTHR_HYS, an event E_VIN_UV is triggered and a pull-down resistor (RPD) is activated. Note that VTHR_RISE is not enough to start the current doubler, see section 9.1.3. Once the adaptor detection is successful, the threshold of the comparator is moved to VUV_RISE.
9.3.2 Battery Voltage Protection
DA9318L/M features differential sense inputs for the battery voltage. The battery voltage is monitored before enabling the current doubler and during current doubler operation to detect over-voltage and under-voltage conditions. Over-voltage conditions longer than tDEGLITCH_OV will disable the current doubler by clearing the CP_EN register and trigger the event E_VBAT_OV. A 20 kΩ pull-down is applied on the OUT pin as long as the status bit S_VBAT_OV remains asserted. Resuming normal operation after the over- voltage event is triggered requires that the event is cleared and that the current doubler is re-enabled either by writing CP_EN or by asserting the nCPEN signal.
High-Efficiency, 10 A, High-Voltage Direct Charger Datasheet Revision 3.2 14-Feb-2022 CFR0011-120-00 26 of 51 © 2022 Renesas Electronics Under-voltage conditions longer than tDEGLITCH_UV will disable the current doubler and trigger the event E_VBAT_UV. Starting the current doubler requires that the event is cleared and that the current doubler is re-enabled either by writing CP_EN or by asserting the nCPEN signal. In addition to battery over-voltage and under-voltage, DA9318L/M features a battery voltage protection based on the ADC results. In the continuous mode of the ADC converter, the result on the VBAT channel (ADC_VBATT_RESULT) is compared against the threshold programmed in the VBAT_WARN_THRSH register bits. If the measurement exceeds the threshold, an event E_VBAT_WARN is triggered. The battery voltage warnings are only enabled in the continuous mode of the ADC and when the VBAT_WARN_THRSH register bits are programmed with a non-zero value.
9.3.3 Input to Output Voltage Protection
The purpose of the input to output voltage (VIN2OUT) protection is to detect when the input-to-output voltage ratio is suitable for the current doubler operation, see section 9.1.5. Fault conditions lasting longer than tDEGLITCH will disable the current doubler by clearing the CP_EN register bit and trigger the event E_VIN2OUT_MIN or E_VIN2OUT_MAX. Resuming normal operation after an event is triggered requires that the event is cleared and that the current doubler is re-enabled either by writing CP_EN or by asserting the nCPEN signal.
9.4 Current Sensing
DA9318L/M features input and output current reporting based on the internal current sense. The current sense information is sampled by the ADC and reported via registers ADC_IIN_RESULT and ADC_IOUT_RESULT. The input and output current sensing does not require an external shunt resistor. Table 10 defines the range and precision for current sensing.
9.4.1 Over-Current Monitoring
DA9318L/M features a programmable over-current monitoring that uses the ADC reading of the input current to detect an over-current condition. The monitoring value can be programmed in the IIN_OC_THRSH register bits. The conversion result (reported via the ADC_IIN_RESULT register bits) is compared to the IIN_OC_THRSH value and an over-current event (E_IIN_OC) is triggered if the measurement value exceeds the threshold. The over-current fault can be configured to either trigger the event, or to trigger the event and clear the current doubler enable (CP_EN). The over- current monitoring is only enabled in the continuous mode of the ADC (ADC_AUTO_CNVRT = 1) and if IIN_OC_THRSH is programmed with a non-zero value.
9.5 Junction Temperature Monitoring
To protect DA9318L/M from damage due to excessive power dissipation the junction temperature (TJUNC) is monitored continuously. The monitoring is split into three temperature ranges TWARN (programmable via TJUNC_WARN_THRSH from 70 °C to 125 °C), TCRIT (140 °C), and TPOR (150 °C). The first level monitoring (TWARN) is implemented by using the ADC. If the junction temperature rises above the first threshold (TWARN), the event E_TJUNC_WARN is asserted. If the event is not masked, this will trigger an interrupt. This first level of temperature supervision is intended for non-invasive temperature control, where the necessary measures for cooling the system down are left to the host software. The status of the TWARN comparator can be read from S_TJUNC_WARN. An interrupt is generated when the temperature crosses the threshold from low to high, or from high to low. After the interrupt, the application processor can read out the comparator status to detect when the temperature drops below the threshold. The second level monitoring (TCRIT) is implemented with a comparator. If the junction temperature continues to rise and crosses the second threshold (TCRIT), an event is triggered (E_TJUNC_CRIT) and DA9318L/M moves to the IDLE mode. Resuming normal operation requires that the junction temperature drops below TCRIT.
High-Efficiency, 10 A, High-Voltage Direct Charger Datasheet Revision 3.2 14-Feb-2022 CFR0011-120-00 27 of 51 © 2022 Renesas Electronics The third level monitoring (TPOR) is implemented with a comparator. Crossing the third threshold causes DA9318L/M to enter SHUTDOWN mode. DA9318L/M stays in SHUTDOWN mode as long as the junction temperature is above TCRIT.
9.6 ADC
DA9318L/M features an 8-bit ADC that can be used to monitor VIN, IIN, VBAT, IOUT, and TJUNC. Table 20 summarizes the ADC channels. The ADC is enabled in IDLE and ACTIVE modes. It features two operational modes: continuous and single shot. By default, the ADC runs in the continuous mode (ADC_AUTO_CNVRT = 1). In this mode, the ADC runs continuously through its channels and updates the results registers (ADC_RES_x). The number of conversions averaged for each result can be controlled using the ADC_AVERAGE register bits. An event (E_ADC_DONE) is triggered only once in the continuous mode, when the first results are ready after enabling the ADC or starting the continuous mode. Measurements can also be taken in single shot mode (ADC_AUTO_CNVRT = 0) via the 2-wire interface by writing 1 to the ADC_SINGLE_CNVRT register bit. Once a conversion is initiated, the result register (ADC_RES_x) of each channel is updated using the averaging set in the ADC_AVERAGE register bits. Once the measurement is done, an event is triggered (E_ADC_DONE) and the measurement of each channel can be read out from the result registers.

9.7 Safety Timer
A safety timer is running whenever DA9318L/M is in ACTIVE mode. The purpose of the safety timer is to detect a condition where the battery does not react to charging as expected. For example, if the voltage of the battery does not rise during constant current charging it is likely that the battery is damaged. This condition is detected by the safety timer. The safety timer is automatically enabled whenever DA9318L/M moves to the ACTIVE mode. If the safety timer expires an event is triggered (E_SAFETY_TIMER) and CP_EN is cleared. Note that the safety timer count is only reset by writing the SAFETY_TIMER_LOAD register. The SAFETY_TIMER_LOAD register should be written before the start of a new charging cycle. Restarting the current doubler after a safety timeout requires that the timeout event is cleared and that the CP_EN bit is asserted. The following conditions will disable the safety timer:
High-Efficiency, 10 A, High-Voltage Direct Charger Datasheet Revision 3.2 14-Feb-2022 CFR0011-120-00 28 of 51 © 2022 Renesas Electronics
- VIN supply removal
- Other fault condition (VOV_ACT, VUV_RISE, VBAT_OV_THRSH, VBAT_UV_THRSH, TCRIT)
9.8 Watchdog Timer
DA9318L/M features a watchdog timer that is intended to monitor the host software during charging and disable the charger in the event of system malfunction. Some of the automatic charging features of DA9318L/M, such as battery temperature profiling, can be disabled and implemented in software instead. Moving the control to software requires tighter supervision than is provided by the charging timer, therefore a separate watchdog timer is provided. Whenever the charger is enabled, the watchdog timer is loaded (via I2C) with a pre-programmed value (WD_TIMER_LOAD) which starts decrementing. In normal operation the application processor should periodically re-initialize the safety timer by writing a new value to the WD_TIMER_LOAD register bits. The value of the counter can be read from the WD_TIMER_COUNT register bits. However, if the timer reaches zero an event (E_WD) is asserted and the charger is automatically disabled. The following conditions will disable the watchdog timer:
- VIN supply removal
- Other fault condition (VOV_ACT, VUV_RISE, VBAT_OV_THRSH, VBAT_UV_THRSH, TCRIT)
9.9 Control Interface
All the output signals of DA9318L/M are driven with an open drain stage. The signals have to be pulled up with external resistors to an IO supply. The inputs are compared to internally generated references VIH and VIL to detect the high and low levels of the signals, respectively. Figure 12 depicts the structure of the control signals.

9.9.1 PWREN
PWREN is a master enable for the DA9318L/M internal blocks and 2-wire interface. It is used to minimize the power consumption of DA9318L/M during NO-POWER mode of the system. It can be tied to a supply rail driven by the PMIC to allow DA9318L/M enter NO-POWER mode whenever the PMIC powers down. 9.9.2 nCPEN nCPEN is an edge sensitive, active low, chip enable signal. It works in conjunction with the CP_EN register bit. A falling edge of nCPEN sets the CP_EN register bit and a rising edge clears it. The current doubler can be started by asserting the nCPEN pin or by writing to CP_EN. The current doubler can be stopped by de-asserting the nCPEN pin or by writing to CP_EN. 9.9.3 nFAULT nFAULT is an active low, open drain, status output. The assertion of any of the following status bits results in the assertion of nFAULT:
- S_VIN_OV
- S_VIN_UV
- S_VBAT_OV
- S_VBAT_UV
- S_VIN2OUT_MAX
- S_VIN2OUT_MIN
- S_TJUNC_CRIT

The assertion of an unmasked event results in the assertion of nIRQ. The nIRQ will not be released until all event registers have been cleared. New events that occur during an event register read will be held until the event register has been cleared, ensuring that the host processor does not miss them. By default all mask bits are asserted. Several sources can generate some events, as depicted in Figure 14. After receiving an interrupt, the source can be detected by reading the associated status registers.

The interface supports operations compatible to Standard, Fast, Fast+ and High-speed mode of the I2C bus specification [6]. Table 21 lists the slave addresses of DA9318L/M. Table 21: Interface Slave Address. Device 7-bit Slave Address 8-bit Slave Address DA9318L/M 0x59 0xB2 (write), 0xB3 (read) Communication on the 2-wire bus is always between two devices, one acting as the master and the other as the slave. DA9318L/M will only operate as a slave. SCL carries the 2-wire clock and SDA carries the bidirectional data. The 2-wire interface is open drain, supporting multiple devices on a single line. The bus lines have to be pulled high by external pull-up resistors (2 kΩ to 20 kΩ). These are often shared between multiple devices connected to the interface. The attached devices only drive the bus lines low by connecting them to ground. As a result, two devices cannot conflict if they drive the bus simultaneously. In Standard/Fast mode the highest frequency of the bus is 400 kHz. The exact frequency can be determined by the application and it does not have any relation to the DA9318L/M internal clock signals. DA9318L/M will follow the host clock speed within the described limitations and does not initiate any clock arbitration or slow down. An automatic interface reset can be triggered in case the clock signal ceases to toggle for > 35 ms (controlled in I2C_TO_EN).
High-Efficiency, 10 A, High-Voltage Direct Charger Datasheet Revision 3.2 14-Feb-2022 CFR0011-120-00 32 of 51 © 2022 Renesas Electronics Bus clear, if the SDA is stuck, is achieved after receiving nine clock pulses. Operation in High-speed mode at 3.4 MHz requires a minimum interface supply voltage of 1.8 V and a mode change in order to enable spike suppression and slope control characteristics compatible to the I2C specification. The High-speed mode can be enabled on a transfer-by-transfer basis by sending the master code (0000 1XXX) at the beginning of the transfer. DA9318L/M does not make a use of clock stretching and delivers read data without additional delay up to 3.4 MHz. Alternatively the interface can be configured to use High-speed mode continuously via I2C_IF_HSM, so that the master code is not required at the beginning of every transfer. This reduces communication overhead on the bus, but limits the attachable bus slaves to compatible devices.
9.10.1 Details of the 2-Wire Protocol
All data is transmitted across the 2-wire bus in 8-bit groups. To send a bit the SDA line is driven at the intended state while the SCL is low. Once the SDA has settled, the SCL line is brought high and then low. This pulse on SCL clocks the SDA bit into the receiver’s shift register. A two byte serial protocol is used containing one address byte and one data byte. Data and address transfer is transmitted MSB first for both read and write operations. All transmission begins with the START condition from the master during which the bus is in IDLE mode (the bus is free). It is initiated by a high-to-low transition on the SDA line, while the SCL is in the high state. A low-to-high transition on the SDA line, while the SCL is in the high state, indicates a STOP condition. Figure 15 illustrates the START and STOP conditions. START STOP SDA SCL Transaction Figure 15: START and STOP Condition Timing The 2-wire bus will be monitored by DA9318L/M for a valid slave address whenever the interface is enabled. It responds immediately when it receives its own slave address. This is acknowledged by pulling the SDA line low during the following clock cycle (white blocks marked with A in the following figures). The protocol for a register write from master to slave consists of a START condition, a slave address, a read/write-bit, 8-bit address, 8-bit data, and a STOP condition. DA9318L/M responds to all bytes with an A. Figure 16 illustrates a register write operation.

After receiving the data, the host sends No Acknowledge and terminates the transmission with a STOP condition, see Figure 17.

9.11 Internal Supplies
The internal supply of DA9318L/M is illustrated in Figure 21, the AVDD regulator is powered from IN and SYS. IN SYS AVDD LDO AVDD CAVDD AGND POR 2.5 V to 5.5 V4.5 V to 13.5 V Figure 21: Internal Supply
9.11.1 AVDD
AVDD is an internal supply that is powered from the higher of IN and SYS. During current doubler operation the input supply to the AVDD regulator is IN and the output voltage is 4 V. If IN is not supplied, the input supply to the AVDD regulator is SYS. If VSYS is not high enough to supply the normal 4 V, the pass device of the AVDD regulator operates as a switch. DA9318L/M remains operational as long as VAVDD is above the POR threshold VPOR_FALL.
9.12 Internal Oscillator
The internal high-speed oscillator generates a signal at fOSC, the internal 6 MHz clock reference. In the IDLE_LP mode the oscillator goes in to a low-power state and changes the frequency to 1 MHz.
9.13 Power Modes
Figure 22 illustrates the power modes of DA9318L/M. The following transitions are high priority and override other transitions in the diagram:
- Critical junction temperature (TJUNC > TCRIT)

9.13.1 NO-POWER Mode
DA9318L/M is in NO-POWER mode when VAVDD is below the VPOR_RISE threshold. RCP is active, as described in section 9.1.1. When IN or SYS is supplied and PWREN is de-asserted, the internal supply AVDD is automatically enabled and when VAVDD rises above the VPOR_RISE threshold, DA9318L/M moves to the INIT (initialization) mode.
9.13.2 SHUTDOWN Mode
The SHUTDOWN mode activates the internal oscillator, adaptor detection, 2-wire interface, and output signals. The 2-wire interface is operational, but as the initialization is not completed, all registers will return their power-on-reset values. Transition to INIT mode is triggered when a travel adaptor is detected.
9.13.3 INITIALIZATION Mode
In the INIT mode, the internal reference, oscillator, and clock generator are enabled. RCP is active, as described in section 9.1.1. DA9318L/M goes through a full initialization including an OTP read. After the initialization is complete, the status registers and events are updated to match the status of the internal protections. The junction temperature is checked, and if it is below the critical level (TCRIT), DA9318L/M moves automatically to the IDLE mode.
9.13.4 IDLE Mode
In the IDLE mode DA9318L/M is fully operational but the current doubler is not enabled. RCP is active, as described in section 9.1.1. If the current doubler is enabled (CP_EN = 1), DA9318L/M enables monitoring features and evaluates the conditions for start-up:
High-Efficiency, 10 A, High-Voltage Direct Charger Datasheet Revision 3.2 14-Feb-2022 CFR0011-120-00 36 of 51 © 2022 Renesas Electronics
- Junction over-temperature (junction temperature exceeds TCRIT)
- Output voltage (VBAT_UV_THRSH < VBAT < VBAT_OV_THRSH)
- Input voltage (VUV_RISE < VIN < VOV_ACT)
- Input to output voltage (VIN2OUT_MIN, VIN2OUT_MAX) If the conditions are met, DA9318L/M soft-starts the current doubler and moves to the ACTIVE mode. If IN is not supplied, the current doubler is disabled (EN_IDLE_LP = 1) and DA9318L/M moves to the LOW-POWER IDLE mode.
9.13.4.1 LOW-POWER IDLE Mode
The LOW-POWER IDLE (IDLE_LP) mode is a low power sub-mode of the IDLE mode. In IDLE mode DA9318L/M is fully operational but the current doubler is not enabled. RCP is active, as described in section 9.1.1. In IDLE-LP mode, most DA9318L/M features are disabled in order to minimize the quiescent current. The only active functions are the AVDD regulator, which ensures the preservation of the logic state, the VTHR_RISE monitoring which detects the assertion of a travel adaptor, and the 2- wire interface. RCP is active. The reduced functionality has the consequence that the status bits in the register map are not automatically updated. Otherwise, IDLE-LP mode is transparent to the system. DA9318L/M reacts identically to register writes and external events in both modes. A transition to IDLE mode is triggered if an input supply is attached and the current doubler is enabled. The transition to IDLE-LP mode can be also controlled with the EN_IDLE_LP bit. By writing EN_IDLE_LP = 0, DA9318L/M never transitions to IDLE-LP mode. If already in IDLE-LP mode, writing EN_IDLE_LP = 0 triggers a transition to IDLE mode.
9.13.5 ACTIVE Mode
In ACTIVE mode the current doubler is enabled. DA9318L/M moves back to IDLE mode in any of the following circumstances:
- The current doubler is disabled (CP_EN = 0)
- The input supply is outside the supported range
- The junction temperature exceeds the critical threshold
- The battery voltage is outside the supported range

11.2 Moisture Sensitivity Level
The Moisture Sensitivity Level (MSL) is an indicator for the maximum allowable time period (floor lifetime) in which a moisture sensitive plastic device, once removed from the dry bag, can be exposed to an environment with a specified maximum temperature and a maximum relative humidity before the solder reflow process. Table 52 defines the MSL classification. For detailed information on MSL levels refer to the IPC/JEDEC standard J-STD-020, which can be downloaded from http://www.jedec.org. The WLCSP package is qualified for MSL 1. Table 52: MSL Classification MSL Level Floor Lifetime Conditions MSL 4 72 hours 30 °C / 60 % RH MSL 3 168 hours 30 °C / 60 % RH MSL 2A 4 weeks 30 °C / 60 % RH MSL 2 1 year 30 °C / 60 % RH MSL 1 unlimited 30 °C / 85 % RH
11.3 WLCSP Handling
Manual handling of WLCSP packages should be reduced to the absolute minimum. In cases where it is still necessary, a vacuum pick-up tool should be used. In extreme cases plastic tweezers could be used, but metal tweezers are not acceptable, since contact may easily damage the silicon chip. Removal of a WLCSP package will cause damage to the solder balls. Therefore a removed sample cannot be reused. WLCSP packages are sensitive to visible and infrared light. Precautions should be taken to properly shield the chip in the final product.
11.4 Soldering Information
Refer to the IPC/JEDEC standard J-STD-020 for relevant soldering information. This document can be downloaded from http://www.jedec.org.
