5 Pin Configuration and Functions

Pin Functions

NUMBER NAME TYPE DESCRIPTION
1 SDA IO(1) Open drain slave I2C serial communication data line. Use with a 10-kΩ pullup resistor (typical).
2 SCL IO Slave I2C serial communication clock input. Use with a 10-kΩ pullup resistor (typical).
3 VSS P Device ground
5 REG18 P Capacitor required for the 1.8-V integrated LDO. Decouple with 2.2-µF ceramic capacitor to VSS.
7 REGIN P Battery voltage input and integrated LDO input. Decouple with 1-µF ceramic capacitor to VSS.
9 SRN AI Analog input pin connected to the internal coulomb-counter peripheral for integrating a small voltage between SRP and SRN where the voltage at SRN will be lower than SRP during a charging event
10 SRP AI Analog input pin connected to the internal coulomb-counter peripheral for integrating a small voltage between SRP and SRN where the voltage at SRP will be higher than SRN during a charging event
12 TS AI Pack thermistor voltage sense (use 103AT-type thermistor). Disable TS with a 10-kΩ resistor to VSS. Do not leave floating.
14 ALERT IO Open drain ALERT output, requires a pullup resistor (typical 10 kΩ). Used as an input to exit SHUTDOWN mode
4, 6, 8,
11, 13		 NC NC No internal connection
(1) IO = Digital input-output, AI = Analog input, P = Power connection, NC = No internal connection
