BQ35100PWR from Texas Instruments, in a TSSOP-14. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VIN | power_in | Optional voltage measurement input; use external scaling circuit for battery voltages exceeding 5 V. |
| 2 | ALERT | tri_state | Active low interrupt open-drain output; external pullup resistor required. |
| 3 | NC | unconnected | Not connected; pin must be connected to VSS. |
| 4 | BAT | power_in | Voltage measurement input accepting 0 to 5 V; can be left floating or tied to VSS if unused. |
| 5 | GE | input | Gauge enable input; internal LDO disconnects from REGIN when driven low. |
| 6 | REGIN | power_in | Internal LDO input accepting 2.7 to 4.5 V; decouple to VSS with 0.1-µF ceramic X5R capacitor. |
| 7 | REG25 | power_out | 2.5-V regulated output of internal LDO; decouple to VSS with 1-µF ceramic capacitor. |
| 8 | VSS | power_in | Device ground; 0 V reference. |
| 9 | SRP | input | Coulomb counter analog input (±0.125 V range) connected to sense resistor nearest BAT- terminal. |
| 10 | SRN | input | Coulomb counter analog input (±0.125 V range) connected to sense resistor nearest PACK- terminal. |
| 11 | TS | input | Pack thermistor voltage sense input for external 103AT NTC thermistor temperature measurement. |
| 12 | VEN | tri_state | Optional open-drain external voltage divider control output. |
| 13 | SCL | input | Slave I2C serial clock input; use 10-kΩ external pullup resistor (typical). |
| 14 | SDA | tri_state | Open-drain slave I2C serial data line; use 10-kΩ external pullup resistor (typical). |
