BQ296100DSGR from Texas Instruments, in a WSON-8-EP(2x2). Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VDD | power_in | Power supply input with operating voltage range 3V to 20V; minimum 4V required for REG output enable. |
| 2 | V4 | input | Fourth cell voltage detection input (V4-V3 measurement) with input range 0V to 5V; requires 1kΩ series resistor and 0.1µF shunt capacitor filter per design requirements. |
| 3 | V3 | input | Third cell voltage detection input (V3-V2 measurement) with input range 0V to 5V; requires 1kΩ series resistor and 0.1µF shunt capacitor filter per design requirements. |
| 4 | V2 | input | Second cell voltage detection input (V2-V1 measurement) with input range 0V to 5V; requires 1kΩ series resistor and 0.1µF shunt capacitor filter per design requirements. |
| 5 | V1 | input | First cell voltage detection input (V1-VSS measurement) with input range 0V to 5V; requires 1kΩ series resistor and 0.1µF shunt capacitor filter per design requirements. |
| 6 | VSS | power_in | Ground reference; electrical connection to IC ground and battery pack negative terminal; must be connected first during cell connection to prevent damage to REG pin. |
| 7 | REG | output | Regulated power output programmed to 3.3V (±3.6% accuracy) with maximum 2mA output current and requiring external 0.47µF to 1µF ceramic capacitor to VSS for stability. |
| 8 | OUT | output | Overvoltage fault signal output with CMOS high-active configuration producing 6V to 8V output voltage when cell voltage exceeds 4.35V threshold; maximum output pull current 4.5mA. |
| 9 | PWPD | passive | Exposed thermal pad; must be soldered to PCB ground plane connection for thermal and mechanical performance of the 2x2mm WSON package. |
