FH2120-ZG
鑫飞宏 · Battery Management · SOT-23-6
FH2120-ZG from 鑫飞宏, in a SOT-23-6. 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 | OD | output | Gate connection terminal for the discharge-control FET. |
| 2 | OC | output | Gate connection terminal for the charge-control FET. |
| 3 | CS | input | Voltage-detection terminal between CS and GND, which also serves as the overcharge detection terminal and the charger detection terminal. |
| 4 | VC | input | Connection terminal for the negative voltage of battery 1 and the positive voltage of battery 2. |
| 5 | VCC | power_in | Positive power supply input terminal, also the connection for the positive voltage of battery 1. |
| 6 | GND | power_in | Negative power supply input terminal, also the connection for the negative voltage of battery 2. |
