13 / 63 page  Data Sheet ADP5350 Rev. B | Page 13 of 63 PIN CONFIGURATION AND FUNCTION DESCRIPTIONS Figure 4. LFCSP Pin Configuration (Top View) Table 9. LFCSP Pin Function Descriptions Pin No. Mnemonic Description 1 INT Processor Interrupt (Active Low). This pin requires an external pull-up resistor. If this pin is not used, it can be left floating. 2 PGOOD Power-Good Signal Output. This open-drain output is the power-good signal for the selected channels. 3 THR Battery Pack Thermistor Connection. 4 BSNS Battery Voltage Sense Pin. 5 ISOB Battery Supply Side Input to Internal Isolation FET/Battery Current Regulation FET. 6 ISOS Charger Supply Side Input to Internal Isolation FET/Battery Current Regulation FET. 7 AGND Analog Ground. 8 CFL1 Power input to the charger regulator. Connect a ceramic filter capacitor between this pin and either PGND1A or PGND1B. 9, 10 PGND1A, PGND1B Power Ground for the Battery Charger. 11, 12 SW1A, SW1B Switching Node for the Battery Charger. 13, 14 VBUSA, VBUSB Power Connection to USB Bus Voltage. 15 SW4 Switching Node for the Boost Regulator. 16 PGND4 Power Ground for the Boost Regulator. 17 VOUT4 Power Output for the Boost Regulator. 18 FB4 Feedback Sensing Input for the Boost Regulator. In standalone mode, connect this pin to a resistor divider from VVOUT4. In LED operation mode, connect FB4 to ground. 19 VIN4 Input Voltage for the Boost Regulator and LDO Control Block. 20 D1 LED 1 Sink Channel. Connect this pin to the cathode of the LED. 21 D2 LED 2 Sink Channel. Connect this pin to the cathode of the LED. 22 D3 LED 3 Sink Channel. Connect this pin to the cathode of the LED. 23 D4 LED 4 Sink Channel. Connect this pin to the cathode of the LED. 24 D5 LED 5 Sink Channel. Connect this pin to the cathode of the LED. 25 VOUT3 Power Output for LDO3. 26 CFL2 Internal Regulator Output for the Fuel Gauge. Connect a ceramic capacitor between this pin and AGND. 27 VIN123 Power Input for LDO1, LDO2, and LDO3. 28 VOUT2 Power Output for LDO2. 29 VOUT1 Power Output for LDO1. 30 SCL I2C Serial Clock. This pin requires an external pull-up resistor. 31 SDA I2C Serial Data. This pin requires an external pull-up resistor. 32 BATOK Battery Status Open-Drain Output Flag (Active High). This pin enables the system when the battery reaches VWEAK. EPAD Exposed Pad (Analog Ground). The exposed pad must be connected and soldered to an external ground plane. 24 D5 23 D4 22 D3 21 D2 20 D1 19 VIN4 18 FB4 17 VOUT4 1 2 3 4 5 6 7 8 INT PGOOD THR BSNS ISOB ISOS AGND CFL1 NOTES 1. EXPOSED PAD (ANALOG GROUND). THE EXPOSED PAD MUST BE CONNECTED AND SOLDERED TO AN EXTERNAL GROUND PLANE. ADP5350 TOP VIEW (Not to Scale) |
