# BQ296216DSGR

**Texas Instruments** · Battery Management · WSON-8-EP(2x2)

BQ296216DSGR 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 | Unregulated power supply input for the device, filtered by a series resistor and a capacitor to VSS. |
| 2 | V4 | input | Voltage sense input for the positive terminal of the fourth cell from the bottom of the pack, requiring a series RC filter. |
| 3 | V3 | input | Voltage sense input for the positive terminal of the third cell from the bottom of the pack, requiring a series RC filter. |
| 4 | V2 | input | Voltage sense input for the positive terminal of the second cell from the bottom of the pack, requiring a series RC filter. |
| 5 | V1 | input | Voltage sense input for the positive terminal of the first (bottom) cell in the pack, requiring a series RC filter. |
| 6 | VSS | power_in | Electrical connection to the IC ground and to the negative terminal of the bottom cell; connect first during cell attachment to avoid REG damage. |
| 7 | OUT | output | Analog overvoltage fault output; CMOS active-high output or open-drain active-low output, used to drive an NMOS fuse-blow FET. |
| 8 | REG | power_out | Regulated power output for external circuits such as an RTC; requires an external ceramic capacitor (0.47 µF minimum) to VSS and supplies up to 2 mA. |
| 9 | PWPD | power_in | Exposed thermal pad; TI recommends connecting it to VSS on the PCB. |
