BQ294703DSGR 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 input power supply, 3V to 20V operating range with 1-2µA typical quiescent current. |
| 2 | V4 | input | Analog input for 4th cell voltage detection from battery pack negative, 0-5V range with <100nA input leakage current. |
| 3 | V3 | input | Analog input for 3rd cell voltage detection from battery pack negative, 0-5V range with <100nA input leakage current. |
| 4 | V2 | input | Analog input for 2nd cell voltage detection from battery pack negative, 0-5V range with <100nA input leakage current. |
| 5 | V1 | input | Analog input for 1st cell voltage detection from battery pack negative, 0-5V range with <100nA input leakage current. |
| 6 | VSS | power_in | Ground connection to IC and battery pack negative terminal. |
| 7 | CD | output | External capacitor connection for programmable overvoltage delay timer, 0-5V range with 1-2 second typical delay at 0.1µF capacitor. |
| 8 | OUT | output | Active high CMOS overvoltage fault signal output, 6V high level (VDD=14.4V) or 250-400mV low level with 4.5mA high and up to 14mA low drive capability. |
| 9 | PowerPAD | power_in | Thermal exposed pad (2.0mm × 2.0mm), recommended connection to VSS for thermal and mechanical performance. |
