9.1 Main Charger

The main charger is a fully featured charger that can operate as a stand-alone device. It is also designed to support an external slave charger. The main charger is responsible for the following functions:

  • Charging control (pre-charge, CC, CV, JEITA)
  • Battery detection
  • Battery activation
  • Battery pre-charge
  • CV-phase
  • IBUS sensing (IBUSM + IBUSS)
  • Reverse-current protection
  • IBATM regulation
  • IBAT sensing (IBATM + IBATS)
  • Battery isolation
  • TBAT monitoring
  • VBAT sensing

9.2 Slave Charger

The slave charger provides a regulated current (IBATS) and it is enabled only in the CC-phase of charging. The slave charger does not feature a VBAT regulation loop, and therefore, does not operate during CV-phase of charging. It is controlled by the application processor. The slave charger is responsible for the following functions:

  • IBATS regulation
  • Hazard detection (VBAT over- and undervoltage) For more details about the slave charger operation and the system integration, please refer to the application note.

10 Functional Description

10.1 Control Signals

10.1.1 EN The EN pin controls the BUCK_EN register. A rising edge sets the register and a falling edge clears it. The rising edge of the EN pin has to occur when DA9155M is in the disabled mode. The application processor can start the Buck by asserting the EN pin or by setting the BUCK_EN bit through the 2-wire interface. The level of the EN pin can be read from S_EN_PIN register. A fault condition in the system (VIN_DROP, VIN_OV, VIN_UV, VBAT_OV, VBAT_UV, VIO_UV, TJUNC_CRIT) de-asserts BUCK_EN and triggers a transition to the disabled mode. If a rising edge of the EN pin occurs while the fault condition remains, the Buck is not enabled and an event indicating a blocked enable is triggered (E_EN_BLOCK). Re-enabling the Buck after a fault condition requires that status and event bits are cleared. The EN pin can be shorted to ground when not used.

Datasheet Revision 3.2 25-Feb-2022 CFR0011-120-00 Rev 5 17 of 37 © 2022 Renesas Electronics 10.1.2 nIRQ nIRQ is a level sensitive interrupt signal. It can be configured either as a push-pull or as an open drain output (IRQ_TYPE), and the polarity can be selected (IRQ_LEVEL). The structure of the interrupt logic is depicted in Figure 11. nIRQ is asserted when an un-masked event is asserted. The nIRQ will not be released until all event registers have been cleared. New events that occur during reading an event register will be held until the event register has been cleared, ensuring that the host processor does not miss them.

The interface supports operations compatible to standard, fast, fast-plus and high speed mode of the I2C bus specification Rev. 3. Communication on the 2-wire bus is always between two devices, one acting as the master and the other as the slave. The DA9155M will only operate as a slave. SCL carries the 2-wire clock and SDA carries the bi-directional 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 –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 DA9155M internal clock signals. DA9155M 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 2W_TO). Bus clear, if the SDA is stuck, is achieved after receiving 9 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. The DA9155M 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 PM_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.

10.2.1 Register Map Paging

The 2-wire interface has direct access to two pages of the register map (up to 256 addresses). The register at address zero on each page is used as a page control register (the LSB of the PAGE register is ignored). Writing to the page control register changes the active page for all subsequent read/write operations unless an automatic return to page 0 was selected by asserting the REVERT register. Alternatively, DA9155M offers a way to access register pages which avoids changing the active page via the PAGE register. DA9155M can respond to multiple consecutive slave addresses and update the PAGE register automatically based on the slave address. For example, when IF_BASE_ADDR = 0x58, the PAGE register responds to the slave address as follows: Slave address = 0x58  PAGE = 0x00 Slave address = 0x59  PAGE = 0x02 Slave address = 0x5A  PAGE = 0x04 Slave address = 0x5B  PAGE = 0x06 The consecutive addresses are obtained by replacing the two LSB in IF_BASE_ADDR with “00”, “01”, “10”, or “11”. This feature can be enabled in the I2C_EXTEND_EN register.

10.2.2 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 state (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 STOP condition is indicated by a low-to-high transition on the SDA line while the SCL is in the high state. The START and STOP conditions are illustrated in Figure 12. START STOP SDA SCL Transaction Figure 12: Timing of the START and STOP Conditions The 2-wire bus will be monitored by DA9155M 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. DA9155M responds to all bytes with an ACK. A register write operation is illustrated in Figure 13.

After receiving the data, the host sends NACK and terminates the transmission with a STOP condition. This is illustrated in Figure 14.

The 2-wire control block then increments the address pointer to the next register address and sends the data to the master. This enables an unlimited read of data bytes until the master sends a NACK directly after receiving the data, followed by a subsequent STOP condition. If a non-existent 2-wire address is read out then the DA9155M will return code zero.

Consecutive (page) write mode is supported if the master sends several data bytes following a slave register address. The 2-wire control block then increments the address pointer to the next 2-wire address, stores the received data, and sends an ACK until the master sends a STOP condition.

10.3 Buck Converter

DA9155M features a Buck converter that provides up to 2.5 A of regulated output current, with IOUT_ACC regulation accuracy. The output current of the Buck can be selected from a control register (BUCK_IOUT). In order to limit inrush current from the power supply, the Buck converter features a soft-start function. Whenever the Buck is enabled or the output current is changed, the output current is ramped to the target value by running through the BUCK_IOUT steps at a rate defined by the START_SLEW and DEF_SLEW_RATE registers. As the names imply, START_SLEW is used when the Buck is enabled and DEF_SLEW_RATE is used when disabling the Buck or changing between IOUT settings. The slew rate timings are summarized in Table 14. Table 14: Slew Rate Timings with Different Register Settings SLEW[2:0] Time per IOUT Step [µs] Ramp Rate [mA/µs] Ramp Time 250 mA to 2.5 A [µs] 0x5 10.67 0.938 2400 0x6 21.30 0.469 4800 0x7 42.70 0.234 9600 The Buck features a programmable peak current limit (BUCK_ILIM), which protects the pass devices and the inductor. Hitting the limit triggers an E_BUCK_ILIM event. During normal operation the E_BUCK_ILIM event should not occur. However, the event can be used as an indication of abnormal system behaviour. The Buck is enabled either by writing directly to a control register BUCK_EN or asserting the EN input. The soft-start feature described above is effective when the Buck is enabled or disabled. The switching frequency is chosen high enough to allow the use of a small 0.47 µH inductor. Furthermore, the switching frequency can be adjusted with the BUCK_FSW and OSC_FRQ registers in order to avoid interference to/from the main charger. The Buck also features an automatic

Datasheet Revision 3.2 25-Feb-2022 CFR0011-120-00 Rev 5 21 of 37 © 2022 Renesas Electronics frequency fold back mode, where the switching frequency is stepwise reduced until a required duty cycle can be achieved. Without the frequency fold back the duty cycle is limited by the Buck’s minimum off-time. It is recommended to configure the switching frequency to 1 MHz when operating with 5 V VIN.

10.4 Safety Timer

DA9155M features a safety timer that is intended to disable the Buck converter in the event of system malfunction during charging. Whenever the Buck is enabled, either through the EN pin or from a register, the safety timer is loaded with a pre-programmed value (TIMER_LOAD) and it starts decrementing. In normal operation the application processor should periodically re-initialize the safety timer by writing a new value to the TIMER_LOAD register. The value of the counter can be read from the TIMER_COUNT register. However, if the timer reaches zero an event is asserted, and the Buck is automatically disabled. The BUCK_EN register is cleared and the Buck is stopped by ramping down the output current at a rate defined in SLEW_RATE. Resuming normal operation requires that the event is cleared.

10.5 VIN Monitoring

VIN is monitored to detect a power supply insertion, and to ensure that VIN is within an acceptable voltage range. The monitoring is illustrated in Figure 18. When VIN is below the VIN2BAT threshold DA9155M stays in the no-power mode. When VIN rises above the VIN2BAT threshold, DA9155M moves to the reset mode where the internal supply and reference are enabled. VIN VBAT VIN_UV IN2BAT VBAT_OV VBAT_UV VREF VIN_OV VIN_DROP Figure 18: VIN Monitoring of DA9155M In reset, disabled, and active mode, VIN is monitored against over- and undervoltage. If over- or undervoltage is detected, an event is triggered (E_VIN_OV, E_VIN_UV), the BUCK_EN register is cleared, and DA9155M moves to disabled mode. Re-enabling the Buck requires that the status and event bits are cleared. During charging VIN is monitored for weak charger or high impedance USB cable detection. If VIN drops below the threshold VIN_DROP, an event is triggered (E_VIN_DROP) and the Buck is automatically disabled. The BUCK_EN register is cleared and the Buck is stopped by ramping down the output current at a rate defined in DEF_SLEW_RATE. The Buck does not start automatically when the VIN rises above the threshold. Resuming normal operation requires that the status and event bits are cleared. This feature is targeted for use cases where the VIN is above the standard

Datasheet Revision 3.2 25-Feb-2022 CFR0011-120-00 Rev 5 22 of 37 © 2022 Renesas Electronics VBUS, in which case the undervoltage lockout is too low to detect a weak supply. By default, VIN_DROP is set to the same voltage as the VIN_UVLO, which effectively disables the VIN_DROP. The status of the VIN monitoring comparators can be read out from the status registers (S_VIN_UV, S_VIN_OV, S_VIN_DROP).

10.6 VBAT Monitoring

The VBAT monitoring is illustrated in Figure 18. The slave charger has to monitor the battery voltage in case of fault conditions during charging, meaning that battery over- and undervoltage have to be detected. DA9155M features two factory programmable settings for handling the monitoring: 1. An overvoltage or undervoltage event triggers an event (E_VBAT_OV, E_VBAT_UV) and the BUCK_EN register is de-asserted. Resuming normal operation requires that VBAT is within normal range and the events are cleared. The supervision of the battery voltage VBAT is done by comparators. 2. An overvoltage or undervoltage event does not disable the Buck converter. Only the status registers are updated (default). The VBAT monitoring status comparators can always be read out from the status registers (S_VBAT_UV, S_VBAT_OV).

10.7 Junction Temperature Supervision

To protect DA9155M from damage due to excessive power dissipation the junction temperature is monitored continuously. The monitoring is split into three temperature ranges TJUNC_WARN (125 °C), TJUNC_CRIT (140 °C), and TJUNC_POR (150 °C). If the junction temperature rises above the first threshold (TJUNC_WARN), the event E_TJUNC_WARN is asserted. If the event is not masked, this will fire 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 TJUNC_WARN comparator can be read from S_TJUNC_WARN. The interrupt is only generated when the temperature crosses the threshold from low to high. After the interrupt, the application processor can read out the comparator status to detect when the temperature drops below the threshold. If the junction temperature continues to rise and crosses the second threshold (TJUNC_CRIT), an event is fired (E_TJUNC_CRIT), the BUCK_EN is de-asserted, and DA9155M moves to the disabled mode. Resuming normal operation requires that TJUNC drops below TJUNC_CRIT and the event is cleared. There is also a third temperature threshold (TJUNC_POR) which causes DA9155M to enter the reset mode. DA9155M stays in the reset mode as long as the junction temperature is above TJUNC_CRIT.

10.8.1 No-Power

The no-power mode is the initial state of DA9155M. Only the VIN-VBAT comparator is active in this state. When VIN rises above VBAT, DA9155M enters the reset mode. All IOs are in their inactive state. The no-power mode is entered whenever VIN drops below VBAT.

10.8.2 Reset

DA9155M enters the reset mode when a power supply is attached and VIN rises above VBAT. In the reset mode, DA9155M will enable the internal reference, the internal supply, execute the reset sequence, and read the OTP. Once the OTP is read and all the VIN conditions are met, DA9155M moves automatically to the disabled mode.

Datasheet Revision 3.2 25-Feb-2022 CFR0011-120-00 Rev 5 24 of 37 © 2022 Renesas Electronics The junction temperature monitoring is also enabled in the reset mode. If a junction over-temperature is detected during operation (TJUNC ≥ TJUNC_POR), DA9155M moves back to the reset mode.

10.8.3 Disabled

In the disabled mode DA9155M is fully functional but the Buck has not been enabled. An event is fired when entering the disabled mode to notify the application processor that the slave charger is ready for operation. If a fault condition exists (TJUNC, VBAT, or VIN), the enable signal is blocked, DA9155M stays in the disabled mode, and an event is triggered. DA9155M moves to the active mode when the Buck is enabled either by asserting the EN signal or by setting the BUCK_EN register.

10.8.4 Active

In the active mode DA9155M is fully functional and the Buck is running. DA9155M moves back to the disabled mode if the Buck is disabled, the safety timer expires, or if there is a fault condition (TJUNC, VBAT, or VIN).

Figure 21: Preliminary PCB Layout for DA9155M Note 1 Component sizes in mm. It is recommended to create a separate quiet ground for the AVDD capacitor connection. The PCB layout should ensure this ground is kept quiet, for example, they should be separated from the main noisy power ground return path. The quiet ground can then be connected to the main ground at the ground plane.
