Pin Functions
TYPE ⁽¹⁾
DESCRIPTION
I
Cell-voltage measurement input. ADC input. TI recommends 4.8 V maximum for conversion accuracy.
IO
Battery-insertion detection input. Power pin for pack thermistor network. Thermistor-multiplexer control pin. Use with
pullup resistor > 1 MΩ (1.8 MΩ typical).
O
Battery charger clock output line for chipset communication. Use without external pullup resistor. Push-pull output.
IO
Battery charger data line for chipset communication. Use without external pullup resistor. Push-pull output.
Chip enable. Internal LDO is disconnected from REGIN when driven low.
I
Note: CE has an internal ESD protection diode connected to REGIN. TI recommends maintaining V_CE ≤ V_REGIN under
all conditions.
P
Regulator input. Decouple with 0.1-μF ceramic capacitor to V_SS.
I
Slave I²C serial communications clock input line for communication with system (master). Open-drain IO. Use with
10-kΩ pullup resistor (typical).
IO
Slave I²C serial communications data line for communication with system (master). Open-drain IO. Use with 10-kΩ
pullup resistor (typical).
IO
SOC state interrupts output. Generates a pulse as described in bq27532-G1 Technical Reference Manual, SLUUB04.
Open-drain output.
AI
Analog input pin connected to the internal coulomb counter where SRN is nearest the V_SS connection. Connect to 5-
to 20-mΩ sense resistor.
AI
Analog input pin connected to the internal coulomb counter where SRP is nearest the PACK– connection. Connect to
5- to 20-mΩ sense resistor.
AI
Pack thermistor voltage sense (use 103AT-type thermistor). ADC input.
P
Regulator output and bq27532-G1 device power. Decouple with 1-μF ceramic capacitor to V_SS. Pin is not intended to
power additional external loads.
P
Device ground
