Pin Functions

PIN TYPE(1) DESCRIPTION
NAME NO.
SRP A1 IA Analog input pin connected to the internal coulomb counter where SRP is nearest the PACK– connection. Connect to 5-mΩ to 20-mΩ sense resistor.
SRN B1 IA Analog input pin connected to the internal coulomb counter where SRN is nearest the Vss connection. Connect to 5-mΩ to 20-mΩ sense resistor.
VSS C1, C2 P Device ground
VCC D1 P Regulator output and bq27530-G1 power. Decouple with 1μF ceramic capacitor to Vss.
REGIN E1 P Regulator input. Decouple with 0.1-μF ceramic capacitor to Vss.
SOC_INT A2 I/O SOC state interrupts output. Open drain output.
BSCL B2 O Battery Charger clock output line for chipset communication. Push-pull output. Note: CE has an internal ESD protection diode connected to REGIN. Recommend maintaining VCE ≤ VREGIN under all conditions.
CE D2 I Chip Enable. Internal LDO is disconnected from REGIN when driven low.
BAT E2 I Cell-voltage measurement input. ADC input. Recommend 4.8V maximum for conversion accuracy.
SCL A3 I Slave I2C serial communications clock input line for communication with system (Master). Open-drain I/O. Use with 10kΩ pull-up resistor (typical).
SDA B3 I/O Slave I2C serial communications data line for communication with system (Master). Open-drain I/O. Use with 10kΩ pull-up resistor (typical).
BSDA C3 I/O Battery Charger data line for chipset communication. Push-pull output.
TS D3 IA Pack thermistor voltage sense (use 103AT-type thermistor). ADC input.
BI/TOUT E3 I/O Battery-insertion detection input. Power pin for pack thermistor network. Thermistor-multiplexer control pin. Use with pull-up resistor >1MΩ (1.8 MΩ typical).
(1) I/O = Digital input/output, IA = Analog input, P = Power connection
