**Texas Instruments** · Battery Management · WSON-6(1.5x1.5)

BQ29707DSET from Texas Instruments, in a WSON-6(1.5x1.5). 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 | NC | unconnected | No connection pin, electrically open. |
| 2 | COUT | output | Charge FET gate drive output driven from the BAT supply; it transitions high to low when a fault is detected, and a 5MΩ resistor from COUT to Pack- discharges the gate when the FET is off. |
| 3 | DOUT | output | Discharge FET gate drive output driven from the BAT supply; it transitions high to low when a fault is detected, and a 5MΩ resistor from DOUT to VSS discharges the gate when the FET is off. |
| 4 | VSS | power_in | Cell negative ground reference pin; overcurrent and cell voltage measurement circuits are referenced to this node. |
| 5 | BAT | power_in | Input supply pin connected to the battery pack positive terminal, with a 0.1µF capacitor to ground for noise filtering; the device operating range is BAT - VSS 1.5V to 8V. |
| 6 | V- | power_in | Voltage sense node used with VSS for fault measurements, with a 2.2kΩ resistor connected between this pin and Pack- in the application; the recommended range is BAT - 25V to BAT. |
