# BQ296106DSGT

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

BQ296106DSGT 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; the datasheet gives an absolute maximum VDD-VSS of -0.3 V to 30 V and a recommended supply range of 3 V to 20 V (4 V minimum when REG output is on). |
| 2 | V4 | input | Sense input for the positive voltage of the fourth cell from the bottom of the stack, with a recommended input voltage range Vn - Vn-1 of 0 V to 5 V. |
| 3 | V3 | input | Sense input for the positive voltage of the third cell from the bottom of the stack, with a recommended input voltage range Vn - Vn-1 of 0 V to 5 V. |
| 4 | V2 | input | Sense input for the positive voltage of the second cell from the bottom of the stack, with a recommended input voltage range Vn - Vn-1 of 0 V to 5 V. |
| 5 | V1 | input | Sense input for the positive voltage of the lowest cell from the bottom of the stack, with a recommended input voltage range V1 - VSS of 0 V to 5 V. |
| 6 | VSS | power_in | Electrically connected to integrated circuit ground and the negative terminal of the lowest cell in the stack; the datasheet gives an absolute maximum input voltage range of -0.3 V to 30 V for the V-sense inputs referenced to VSS. |
| 7 | REG | power_out | Regulated supply output that requires an external ceramic capacitor for stability; the absolute maximum REG-VSS range is -0.3 V to 3.6 V. |
| 8 | OUT | output | Analog output drive for an overvoltage fault signal, provided as a CMOS output (high) or open-drain (active low); the absolute maximum OUT-VSS is -0.3 V to 30 V. |
| 9 | PWPD | passive | Exposed thermal pad; TI recommends connecting the exposed pad to VSS on the PCB. |
