PIN DIAGRAM PIN FUNCTIONS PIN TYPE(1) DESCRIPTION NAME NO. BI/TOUT 1 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 >1M Ω (1.8 MΩ typical). REG25 2 P 2.5 V output voltage of the internal integrated LDO. REGIN 3 P The input voltage for the internal integrated LDO. BAT 4 I Cell voltage measurement input. ADC input. Vcc 5 P Processor power input. Decouple with 0.1mF ceramic capacitor minimum. Vss 6 P Device ground SRP 7 IA Analog input pin connected to the internal coulomb counter where SRP is nearest the PACK-connection. Connect to 5-m Ω to 20-mΩ sense resistor. SRN 8 IA Analog input pin connected to the internal coulomb counter where SRN is nearest the VSS-connection. Connect to a 5-m Ω to 20-mΩ sense resistor. TS 9 IA Pack thermistor voltage sense (use 103AT-type thermistor). ADC input SDA 10 I/O Slave I2C serial communications data line for communication with system (Master). Open-drain I/O.
