# BQ294582DRVR

**Texas Instruments** · Battery Management · WSON-6-EP(2x2)

BQ294582DRVR from Texas Instruments, in a WSON-6-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 | V3 | input | Sense input for positive voltage of the third cell from the bottom of the stack. |
| 2 | V2 | input | Sense input for positive voltage of the second cell from the bottom of the stack. |
| 3 | VSS | power_in | Electrically connected to IC ground and negative terminal of the lowest cell in the stack. |
| 4 | V1 | input | Sense input for positive voltage of the lowest cell in the stack. |
| 5 | VDD | power_in | Power supply (unregulated input power source for the IC, recommended 3 V to 25 V). |
| 6 | OUT | output | Output drive for external N-channel FET gate; transitions high after an overvoltage condition is detected and the programmed delay timer expires, and resets low if cell voltage falls below the OV threshold before the delay expires. |
| 7 | PWRPAD | power_in | Exposed thermal/power pad; must be electrically connected to VSS on the PCB for proper operation. |
