BQ294704DSGT 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 (3V to 20V operating range); connect with series resistor (100Ω typical) and 0.1µF decoupling capacitor to VSS. |
| 2 | V4 | input | Analog input for fourth battery cell voltage measurement from battery pack bottom (0-5V range); add 1kΩ series resistor and 0.1µF capacitor to VSS for noise filtering. |
| 3 | V3 | input | Analog input for third battery cell voltage measurement from battery pack bottom (0-5V range); add 1kΩ series resistor and 0.1µF capacitor to VSS for noise filtering. |
| 4 | V2 | input | Analog input for second battery cell voltage measurement from battery pack bottom (0-5V range); add 1kΩ series resistor and 0.1µF capacitor to VSS for noise filtering. |
| 5 | V1 | input | Analog input for lowest battery cell voltage measurement (0-5V range); add 1kΩ series resistor and 0.1µF capacitor to VSS for noise filtering. |
| 6 | VSS | power_in | Ground connection to IC and negative terminal of lowest battery cell; input leakage current <100nA when all cells remain below overvoltage protection threshold. |
| 7 | CD | output | External delay timer capacitor connection; upon overvoltage detection IC charges capacitor and then discharges at fixed current to VSS over 1-2 seconds nominal (0.1µF capacitor); includes timeout detection for capacitor open or short circuit faults. |
| 8 | OUT | output | CMOS active-high overvoltage fault signal output; sources minimum VDD-0.3V (4.5mA) during overvoltage condition and sinks 250-400mV (up to 14mA) during normal operation for driving external NMOS FET gate. |
| 9 | PowerPAD | power_in | Exposed thermal pad for heat dissipation and mechanical performance; TI recommends connecting to VSS. |
