BQ34210IPWRQ1 from Texas Instruments, in a TSSOP-14. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | SDA | bidirectional | Open-drain slave I2C serial communication data line, used with a 10-kΩ pullup resistor (typical). |
| 2 | SCL | bidirectional | Slave I2C serial communication clock input, used with a 10-kΩ pullup resistor (typical). |
| 3 | VSS | power_in | Device ground. |
| 4 | NC | unconnected | No internal connection. |
| 5 | REG18 | power_out | Capacitor required for the 1.8-V integrated LDO, decoupled with a 2.2-µF ceramic capacitor to VSS; not a supply pin (VREG18 absolute maximum -0.3 V to 2 V). |
| 6 | NC | unconnected | No internal connection. |
| 7 | REGIN | power_in | Battery voltage input and integrated LDO input, decoupled with a 1-µF ceramic capacitor to VSS (VREGIN absolute maximum -0.3 V to 6 V). |
| 8 | NC | unconnected | No internal connection. |
| 9 | SRN | input | Analog input to the internal coulomb-counter for integrating a small voltage between SRP and SRN; SRN is lower than SRP during a charging event. |
| 10 | SRP | input | Analog input to the internal coulomb-counter for integrating a small voltage between SRP and SRN; SRP is higher than SRN during a charging event. |
| 11 | NC | unconnected | No internal connection. |
| 12 | TS | input | Pack thermistor voltage sense for a 103AT-type thermistor; disable with a 10-kΩ resistor to VSS and do not leave floating. |
| 13 | NC | unconnected | No internal connection. |
| 14 | ALERT | bidirectional | Open-drain ALERT output requiring a pullup resistor (typical 10 kΩ), also used as an input to exit SHUTDOWN mode. |
