’99.5.20 Multi LDOs for Cellular-phone R5310L series Rev.1.10 - 1 - I OUTLINE The R5310L Series are Multi LDO regulators for power management of cellular phones. All of regulators are low noise and extremely low quiescent current by CMOS process. Each of these ICs consists of eight LDOs, voltage detectors, battery monitor, three LED drivers, and a ringer driver. Each of them can be controlled by CPU via 3-wire serial interface. These ICs make it possible to integrate almost power management and analog drivers in cellular-phone systems. The output voltage of two regulators are externally programmable, and other regulators are able to set different output voltage independently by laser trim as well as detector thresholds. A tiny 32-pin LQFP, 0.5mm lead pitch, is available. I FEATURES except programmable VRs. Low Temperature-Drift-Coefficients of Output Voltage and 150mV at 80mA for VR2 60dB at 1kHz for VR6 and VR7 detectors and drivers. Adjusting output voltage for VR3/4 by 8 bit. I APPLICATIONS Portable Phones such as GSM, PDC and CDMA as well as other analog phones. Power supply for battery-powered appliances.

Rev.1.10 - 13 - I FUNCTIONAL DESCRIPTION 3-wire Serial Interface 1-1. Data Transfer Summary SCK CSB DATA D10 D11 D12 D13 D14 D15 All data transfers are initiated by driving the CSB input low. The CSB input serves two functions. First, CSB turns on the control logic which allows access to the shift register for the address/command sequence. Second, the CSB signal provides a method of terminating data transfer. A clock cycle is a sequence of a falling edge followed by a rising edge. For data inputs, data must be valid during the rising edge of the clock. All data transfer terminates if the CSB input is high. Data transfer is illustrated as above. 1-2. Command Byte The Command byte is shown as above. Each data transfer is initiated by a command byte. The LSB (bit zero) must be a logic zero. An any data for each of bit six and bit seven which might be zero or one, is ignored. Bits one through five specify the designated registers to be input. The command byte is always input starting with the LSB (bit zero). 1-3. Data Input Following the eight SCK cycles that input a write command byte, a data byte is input on the rising edge of the next eight SCK cycles. And any successive instruction set which consists of command byte and data byte is allowable. The data byte is always input starting with the LSB (bit zero). 1-4. Regulator Switch Each of regulators can be enabled or disabled independently. In the VR switch register, designations for each of seven regulators' ON/OFF can be written to bit zero through six. Bit seven is ignored. 1-5. Battery Monitor / LED Drivers / Ringer Controller An analog output of cell voltage monitor is available with enable switch. Three of constant voltage outputs for LEDs and a ringer controller can be independently ON/OFF. All of those enable switches are controlled by output port register. Bit zero and one through three are for enable switch of battery monitor and LED drivers respectively. Bit four through six is input digit of electronic volume for ringer controller, bit four is defined as the LSB. Bit seven is enable switch for ringer controller. 1-6. Programmable Voltage Regulators /VR3, 4 The output voltage of VR3 and VR4 can be controlled externally by written data to the VR3/VR4 output registers. register is the LSB.

Rev.1.10 - 15 - 1-8. Operation after Interrupt Procedure In the case that CSB input becomes to high by interrupting while a command-set which has not yet been acknowledged, the command-set is disabled by internal reset signal, therefore, after this case, transaction should be executed from the initial condition. Voltage Regulators Embedded 8 regulators are classified into 4 groups as follows by their characteristics: [High Speed Type] VR1, 2, 5, 7 With High ripple rejection (Typ. 65dB at 1kHz) and Low Noise, they are suitable for RF and analog circuits. And the load transient response is also good, therefore they are recommendable for DSP which requires fast dynamic response to load current. [Adjustable Output Voltage Type] VR3, 4 They include 8-bit D/A converter (guaranteed monotonous increase) each, users can select output voltage in a range by 3- wire serial interface control. They are suitable for various applications which do not require much load current (Max. 20mA), such as PA bias, AGC, LCD luminance adjuster and can be used as voltage references. [Boost Type] VR6 VR6 is used with an external PNP transistor and can supply large output current. This regulator is always ON, therefore its supply current is enough minimized to save invalid current by design (Typ. 6µA). [For Vibrator] VR8 VR8 can drive a vibrator (which requires 1.3V as a supply voltage) directly. Voltage Detectors VD1 monitors the voltage of VR6, when the voltage becomes lower than setting detector threshold voltage, DOUT1 pin becomes “L”, and internal logic is initialized, furthermore does not accept input signal. It is suitable for reset CPU. Output type is Nch open drain and pull-up resistance to VR6. Setting output delay time (Reset Released Delay Time) is possible with connecting an external capacitance to CD pin. The formula which shows the relation between External capacitance value (CD) and output delay time is as follows: tD=0.67×106×CD VD2 monitors VDD voltage, when the voltage becomes lower than setting output voltage threshold, DOUT2 becomes “L”, and disables VR6. It is suitable for detecting cutting off a battery voltage in a flash and can be used to set a operation starting voltage. Output Type is CMOS and its “H” level equals to voltage of ROUT6. VD3 monitors also VDD voltage, when the voltage becomes higher than setting output threshold, VD3 disables VR6. It is necessary to protect circuits from large input voltage. VD4 monitors the voltage of VR6, when the voltage becomes higher than setting output threshold, it disables VR6 and protect a coin battery for backup. When ROUT6 is equal or less than setting output threshold, VR6 turns on again. Thus, the operation is repeated until VR6 outputs normal voltage. Ringer Controller Ringer controller is composed with an external PNP transistor. It can control a Ringer in the range from 6Ω to 32Ω. By 3-wire interface controller, ON and OFF, 3bit electrical volume can be controlled. The Output is also controlled to accept “ON” command and input signal of TONE pin via 3-wire interface, thus it can generate any melody. Output condition via 3- wire interface controller inputs and TONE input is shown below: 3-wire input TONE input Ringer Output Supply Current (for Ringer Controller Circuit Part) 0 (OFF) 0 or 1 OFF (almost 0µA) 1 (ON) OFF (standby) (approximately 500µA) 1 (ON) ON (approximately 100µA (only for internal circuit))

Rev.1.10 - 16 - LED Drivers 3 LED drivers are embedded and each of them can control independently, and ON/OFF condition can be controlled via 3-wire interface. POUT1 is applicable for display of receiving a call. Output is controlled with “ON” command or input signal for TIMER pin via 3-wire interface, lighting and flashing can be set freely. POUT2 can be used to drive an LCD back-light, POUT3 is for a back-light for keys. POUT2 and POUT3 is controlled only via 3-wire interface. The Source for POUT1 to 3 is Vp pin. Users can connect it to VDD or ROUT6. Output type is CMOS, thus they can be used as general output ports. Voltage Monitor Voltage monitor is composed with connecting a Pch MOS switch to an upper part of divider resistors. It can be “ON” and “OFF” via 3-wire interface. When it is “ON” state, the voltage of monitor pin or BMON1 is divided with a specific ratio and output to BOUT1 pin. When it is “OFF” state, BMON1 is on high impedance condition, thus BOUT1 is pulled down through a resistance (the value is approximately 8kΩ) to GND.

Rev.1.10 - 17 - I TECHNICAL NOTES G Operation with rising and falling of Supply Voltage Supply voltage condition --- from 0V to a designated voltage To make the explanation be easier, we call a voltage which is monitored and rising voltage threshold, as “Released Voltage”. On the contrary, we call the falling voltage threshold as “Detector Threshold Voltage”. And the difference between them is specified as a Hysteresis Voltage. While the supply voltage is from 0V to VD2 (Released Voltage), all the circuits except VDs are “OFF” state, thus both levels of DOUT1 and 2 are “L”. However, we cannot guarantee the operation with a VDD at voltage below the minimum operating voltage (VDDMIN) with both a rising and a falling conditions. When the supply voltage crosses over the Released Voltage for VD2, DOUT2 becomes “H” and VR6 is enabled. Further, when ROUT6 crosses over the Released Voltage for VD1, after a setting delay time by an external capacitor to CD pin, DOUT1 becomes “H”, then internal logic circuits and reset condition for input control pins (3-wire interface inputs and CSWx etc.) are released. Therefore circuits' operations can become to control by these input pins. Supply voltage condition --- from a designated voltage to 0V When the supply voltage becomes lower than Detector Threshold Voltage for VD2, DOUT2 becomes “L” and disables VR6. Further, VR6 level becomes lower than Detector Threshold Voltage for VD1, then DOUT1 becomes “L” and reset internal logic circuits and input controller pins (3-wire inputs and CSWx etc.) Then all the circuits except VDs are OFF (See the Note below), and input signals for control are not accepted. The lower voltage than this is as same as above. <Note> As for VR1, when supply voltage is equal or less than Detector Threshold Voltage for VD2, output is indefinite (ON/OFF). At this condition, both CSW1 pin input and 3-wire controller inputs cannot be accepted. This operation could cause a problem on your system, and should be considered enough.
