BQ29737DSER 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, electrically open. |
| 2 | COUT | output | Gate Drive Output for Charge FET that transitions from high to low when a fault is detected to turn off the charge FET. |
| 3 | DOUT | output | Gate Drive Output for Discharge FET that transitions from high to low when a fault is detected to turn off the discharge FET. |
| 4 | VSS | power_in | Ground pin serving as cell negative ground reference for internal circuits and overcurrent protection measurements. |
| 5 | BAT | power_in | Supply input pin for the device connected to positive terminal of battery pack requiring 0.1µF input capacitor to ground for noise filtering. |
| 6 | V- | power_in | Voltage sense node for measuring fault detection conditions in conjunction with VSS, with current sink capability of 8-24µA to VSS at VBAT=3.8V. |
