XB3306D

XySemi · Battery Management · SOT-23-3

XB3306D from XySemi, in a SOT-23-3. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VM input Negative terminal of the battery pack sense input. The internal FET switch connects this pin to GND during normal operation; used to sense charger/load presence and overcurrent (VM-to-GND voltage). Absolute max: -6 V to +10 V.
2 VDD power_in Positive power supply pin, tied to the positive terminal of the battery cell (BAT+) through a 100 Ω series resistor with a 0.1 µF decoupling cap to GND. Absolute max: -0.3 V to +6 V.
3 GND power_in Ground reference; connect to the negative terminal of the battery cell (BAT-). Internal power MOSFET switch connects the pack negative (VM) to this pin during normal operation.
