FH8208 from XIN FEI HONG, 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 | GND | power_in | Ground pin. |
| 2 | GND | power_in | Ground pin. |
| 3 | VDD | power_in | Power supply pin; absolute maximum input voltage -0.3V to 6V, connected to the battery positive through a 1kΩ resistor with 0.1μF capacitor to GND. |
| 4 | VM | bidirectional | Negative terminal of the battery pack; the internal FET switch connects this terminal to GND, with absolute maximum input voltage -6V to 10V. |
| 5 | VM | bidirectional | Negative terminal of the battery pack; the internal FET switch connects this terminal to GND, with absolute maximum input voltage -6V to 10V. |
