XB5350A

XySemi · Battery Management · SOT-23-5

XB5350A 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, for vendor use only 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 pin; the VDD input pin voltage absolute maximum range is -0.3 to 6 V.
4 VM passive Negative terminal of the battery pack; the internal FET switch connects this terminal to GND, and the VM input pin voltage absolute maximum range is -6 to 10 V.
5 VM passive Negative terminal of the battery pack; the internal FET switch connects this terminal to GND, and the VM input pin voltage absolute maximum range is -6 to 10 V.
