**XIN FEI HONG** · Battery Management ICs · DFN-4-EP(1x1)

FH8614G1 from XIN FEI HONG, in a DFN-4-EP(1x1). 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 | Chip supply pin, with a recommended supply range of 1.5 V to 5 V and an absolute maximum of -0.3 V to 6 V. |
| 2 | GND | power_in | Chip ground, connected to the battery negative terminal. |
| 3 | GND | power_in | Chip ground, connected to the battery negative terminal. |
| 4 | VM | input | Source of the internal MOSFET, connected to the load or charger negative; VM-to-GND input voltage is limited to -6 V to 10 V (absolute maximum). |
| 5 | EPAD | power_in | Exposed thermal pad (heat sink), connected to the battery negative terminal. |
