BQ294700DSGT 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 power supply input, recommended 3V to 20V, absolute maximum 30V. |
| 2 | V4 | input | Cell voltage sensing input for fourth cell from battery bottom (V4-V3 differential), 0-5V input range, -0.3V to 30V absolute maximum. |
| 3 | V3 | input | Cell voltage sensing input for third cell from battery bottom (V3-V2 differential), 0-5V input range, -0.3V to 30V absolute maximum. |
| 4 | V2 | input | Cell voltage sensing input for second cell from battery bottom (V2-V1 differential), 0-5V input range, -0.3V to 30V absolute maximum. |
| 5 | V1 | input | Cell voltage sensing input for lowest cell (V1-VSS differential), 0-5V input range, -0.3V to 30V absolute maximum. |
| 6 | VSS | power_in | Ground return, electrical connection to IC ground and negative terminal of lowest battery cell, absolute maximum 30V. |
| 7 | CD | output | Delay timer capacitor connection; IC charges and then discharges external capacitor for overvoltage detection delay timing, 0-5V range, -0.3V to 30V absolute maximum. |
| 8 | OUT | output | Overvoltage fault signal output (CMOS active high configuration); outputs 250-400mV low (100µA sink) at normal condition, outputs 6V typical / VDD-0.3V max (4.5mA source) when overvoltage detected. |
| 9 | PWPD | power_in | Exposed thermal pad for die cooling; Texas Instruments recommends soldering to VSS plane on PCB for thermal and mechanical performance. |
