XB5556G 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; not used by the application. |
| 2 | GND | power_in | Ground; connect this pin to the negative terminal of the battery. |
| 3 | VDD | power_in | Power supply pin; the absolute maximum VDD input pin voltage is -0.3 V to 6 V. |
| 4 | VM | passive | Negative terminal of the battery pack, connected to GND through the internal FET switch; the absolute maximum VM input pin voltage is -6 V to 10 V. |
| 5 | VM | passive | Negative terminal of the battery pack, connected to GND through the internal FET switch; the absolute maximum VM input pin voltage is -6 V to 10 V. |
