XB6366D

XySemi · Battery Management ICs · DFN-6-EP(2x2)

XB6366D from XySemi, in a DFN-6-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 Power supply pin; the VDD input pin voltage is rated -0.3 to 6 V.
2 GND power_in Ground pin, connected to the negative terminal of the battery.
3 GND power_in Ground pin, connected to the negative terminal of the battery.
4 VM passive Negative terminal of the battery pack, connected to GND through the internal FET switch; the VM input pin voltage is rated -6 to 10 V.
5 VM passive Negative terminal of the battery pack, connected to GND through the internal FET switch; the VM input pin voltage is rated -6 to 10 V.
6 VM passive Negative terminal of the battery pack, connected to GND through the internal FET switch; the VM input pin voltage is rated -6 to 10 V.
7 EPAD passive Exposed pad that must be connected to a massive metal GND.
