These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.

PIN FUNCTIONS
DESCRIPTION
I/O
Battery-insertion detection input. Power pin for pack thermistor network. Thermistor-multiplexer control
pin. Open-drain I/O. Use with pull-up resistor >1MΩ (1.8 MΩ typical).
P
2.5 V output voltage of the internal integrated LDO.
P
Regulator input. Decouple with 0.1μF ceramic capacitor to Vss.
I
Cell voltage measurement input. ADC input.
P
Processor power input. Decouple with 0.1μF ceramic capacitor minimum.
P
Device ground
IA
Analog input pin connected to the internal coulomb counter with a Kelvin connection where SRP is
nearest the PACK– connection. Connect to 5-mΩ to 20-mΩ sense resistor.
IA
Analog input pin connected to the internal coulomb counter with a Kelvin connection where SRN is
nearest the Vss connection. Connect to 5-mΩ to 20-mΩ sense resistor.
IA
Pack thermistor voltage sense (use 103AT-type thermistor). ADC input
I/O
Slave I²C serial communications data line for communication with system (Master). Open-drain I/O.
Use with 10-kΩ pull-up resistor (typical).
I
Slave I²C serial communications clock input line for communication with system (Master). Open-drain
I/O. Use with 10-kΩ pull-up resistor (typical).
O
General Purpose open-drain output. May be configured as Battery Low, Battery Good, or to perform
interrupt functionality.
(1) I/O = Digital input/output; IA = Analog input; P = Power connection.
