XB5351A0

XySemi · Battery Management · SOT-23-5

XB5351A0 from XySemi, in a SOT-23-5. 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 VT unconnected Test pin, only for vendor use and not to be used by the application.
2 GND power_in Ground; connect the negative terminal of the battery to this pin.
3 VDD power_in Power supply input; the VDD input pin voltage is limited to -0.3 V to 6 V (absolute maximum).
4 VM passive Negative terminal of the battery pack, connected to GND through the internal FET switch; the VM input pin voltage is limited to -6 V to 10 V (absolute maximum).
5 VM passive Negative terminal of the battery pack, connected to GND through the internal FET switch; the VM input pin voltage is limited to -6 V to 10 V (absolute maximum).
