BQ29704DSER

Texas Instruments · Battery Management · WSON-6(1.5x1.5)

BQ29704DSER 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 pin, electrically open.
2 COUT output Gate drive output for the charge FET, driven from the BAT supply and pulled to Pack- through a 5MΩ resistor for gate discharge when the FET is off.
3 DOUT output Gate drive output for the discharge FET, driven from the BAT supply and pulled to VSS through a 5MΩ resistor for gate discharge when the FET is off.
4 VSS power_in Cell negative ground reference pin, against which the cell voltage and overcurrent measurements are referenced.
5 BAT power_in Positive input supply connected to the battery pack positive terminal, with a 0.1µF filter capacitor to ground; recommended positive input voltage is -0.3 V to 8 V.
6 V- power_in Voltage sense node for charge and discharge overcurrent measurement, with a 2.2kΩ resistor to Pack-; negative input voltage range is BAT - 25 V to BAT.
