# XB5352A

**XySemi** · Battery Management · SOT-23-5

XB5352A 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 | passive | Test pin (测试脚); the datasheet gives no electrical limit or operating function for this pin, so it should be treated as a test pad and not used as a circuit connection. |
| 2 | GND | power_in | Ground terminal, connected to the negative terminal of the battery cell; the internal discharge FET switches VM to this pin. |
| 3 | VDD | power_in | IC supply pin; the absolute maximum input voltage on VDD is -0.3 V to 6 V. |
| 4 | VM | input | Negative terminal of the battery pack (shared with pin 5); the internal FET switch connects it to GND, and the absolute maximum VM input voltage is -6 V to 10 V. |
| 5 | VM | input | Negative terminal of the battery pack (shared with pin 4); the internal FET switch connects it to GND, and the absolute maximum VM input voltage is -6 V to 10 V. |
