BQ296103DSGR from Texas Instruments, in a WSON-8-EP(2x2). 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 | VDD | power_in | Power supply input; absolute maximum -0.3V to 30V, recommended 3V to 20V. |
| 2 | V4 | input | Cell 4 voltage detection input monitoring (V4 - V3); recommended 0V to 5V range. |
| 3 | V3 | input | Cell 3 voltage detection input monitoring (V3 - V2); recommended 0V to 5V range. |
| 4 | V2 | input | Cell 2 voltage detection input monitoring (V2 - V1); recommended 0V to 5V range. |
| 5 | V1 | input | Cell 1 voltage detection input monitoring (V1 - VSS); recommended 0V to 5V range. |
| 6 | VSS | power_in | Ground reference; electrical connection to IC ground and battery pack negative terminal. |
| 7 | REG | output | Regulated power output 3.3V nominal, maximum output current 2mA, absolute range -0.3V to 3.6V. |
