ACT81460 Rev 1.0, 18-Dec-2018 PIN DESCRIPTIONS PIN NAME DESCRIPTION
A1 VIN VIN power input System Voltage (system output of smart switch / linear charger). Input voltage to buck A2/B2 VSYS converters A3/B3 VBAT Charging Power Output pin. Positive side of battery connects to VBAT. Sense Pin for Battery Voltage. Kelvin connect VBATS close the battery to sense the battery A4 VBATS voltage. A5 OUTL2 LDO2 output pin. This is also the LDO2 feedback pin. A6 OUTL1 LDO1 output pin. This is also the LDO1 feedback pin. A7 VINB2 Dedicated input pin for BUCK2 B1 Charge current setting pin. Connect a resistor from ISET to AGND to program the maxi- ISET mum charge current. System Voltage (system output of smart switch / linear charger). Input voltage to buck A2/B2 VSYS converters A3/B3 VBAT Charging Power Output pin. Positive side of battery connects to VBAT. B4 Battery temperature sensing input. Connect a negative temperature coefficient thermistor NTC from TH to AGND. This pin provides a constant current output and the voltage at this pin is used for temperature calculation. B5 VINL2 Dedicated power input pin for LDO2 B6 VINL1 Dedicated power input pin for LDO1 B7 SW2 Switch pin for BUCK2 C1 VBST Boost output pin C2 ISNS Back light LED current sense pin for Boost regulator C3 GPIO2 GPIO2. Typically defined as nRESET, but can be configured for other functionality. C4 NC No Connection, this is floating so it can be tied to the adjacent VIO_IN or left floating C5 Digital Input Reference Voltage Input. Connect a 0.1uF ceramic capacitor between VIN_IN VIO_IN and AGND. Used for CMOS output reference voltage. C6 FB_B2 Feedback pin for Buck2. Kelvin connect to the Buck2 output capacitors. C7 Power Ground pin for Buck2. The Buck2 input capacitor must be connected directly to PGND2 PGND2. D1 SWBST Switch pin for Boost Regulator D2 Power Ground pin for the Buck-Boost and Boost. The Buck-Boost input and output capac- PGND34 itors must be connected directly to PGND34. The Boost output capacitors must be directly connected PGND34. All PGND34 pins must be connected together. D3 GPIO1 GPIO1. Typically defined as nIRQ, but can be configured for other functionality D4 SDA I2C Data Input and Output. Needs an external pull up resistor. D5 SCL I2C Clock Input. Needs an external pull up resistor. D6 AGND Analog Ground D7 AGND Analog Ground
