XB3306A

XySemi · Battery Management · SOT-23

XB3306A from XySemi, in a SOT-23. 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 VM passive Negative terminal of the battery pack (charger/load negative); the internal FET switch connects it to GND, with an internal RVMS of 100 kΩ to GND and RVMD of 320 kΩ to VDD, and its abs max input voltage is -6 to 10 V.
2 VDD power_in IC supply pin connected to the battery cell positive terminal, abs max input voltage -0.3 to 6 V.
3 GND power_in Ground pin, connected to the negative terminal of the battery cell.
