BQ294604DRVR from Texas Instruments, in a WSON-6-EP(2x2). 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 | NC | unconnected | No connection. |
| 2 | V1 | input | Cell positive voltage detection input; recommended input voltage 0-5V, absolute maximum 8V. |
| 3 | VSS | power_in | Ground connection to IC and negative cell terminal; must be externally connected to CELL- terminal. |
| 4 | VSS | power_in | Ground connection to IC and negative cell terminal; must be externally connected to CELL- terminal. |
| 5 | VDD | power_in | Power supply input; recommended voltage 3-8V, absolute maximum 30V; supply current 1-2µA typical. |
| 6 | OUT | output | Output driver for external N-channel MOSFET; output voltage VDD-0.3V minimum when overvoltage detected, output voltage 250-400mV when V1-VSS below threshold. |
| 7 | PWRPAD | power_in | Thermal pad; VSS connection to printed circuit board for thermal and mechanical performance; must be soldered to board. |
