BQ294701DSGR

Texas Instruments · Battery Management · WSON-8-EP(2x2)

BQ294701DSGR 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 IC supply input, recommended 3 V to 20 V (VDD-VSS) with absolute maximum 30 V; a series resistor limits current and a capacitor to ground filters noise.
2 V4 input Sense input for the positive voltage of the fourth (top) cell in the stack, with recommended input range 0 V to 5 V and absolute maximum of 30 V; requires a series RC filter at the input.
3 V3 input Sense input for the positive voltage of the third cell from the bottom, with recommended input range 0 V to 5 V and absolute maximum of 30 V; requires a series RC filter at the input.
4 V2 input Sense input for the positive voltage of the second cell from the bottom, with recommended input range 0 V to 5 V and absolute maximum of 30 V; requires a series RC filter at the input.
5 V1 input Sense input for the positive voltage of the bottom cell in the stack, with recommended input range 0 V to 5 V and absolute maximum of 30 V; requires a series RC filter at the input.
6 VSS power_in IC ground, connected to the negative terminal of the bottom cell; absolute maximum rating −0.3 V to 30 V relative to VSS for the other pins.
7 CD output External delay capacitor connection that sets the overvoltage delay tCD = K × CCD (K = 10 to 20 s/µF, so 0.1 µF gives 1 s to 2 s); shorting CD to VSS enables the customer test mode with delay of 170 ms maximum.
8 OUT output Overvoltage fault signal output, factory-set as CMOS active-high or open-drain active-low; the open-drain version requires an external pull-up resistor and absolute maximum is 30 V to VSS.
9 PowerPAD power_in Exposed thermal pad that TI recommends connecting to VSS on the PCB and that must be soldered to the board for thermal and mechanical performance.
