FH4056C
鑫飞宏 · Battery Management · ESOP-8
FH4056C from 鑫飞宏, in a ESOP-8. 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 | NC | unconnected | No-connect pin (空脚) with no internal function. |
| 2 | PROG | bidirectional | Sets the constant charge current through a resistor to GND (RPROG) and monitors the charge current through the voltage on this pin. |
| 3 | GND | power_in | Ground reference pin for the charger. |
| 4 | VCC | power_in | Power input pin; charging operates with VCC from 4.25 V to 6.0 V (typical 5.0 V), and the VCC undervoltage lockout threshold is 3.7 V on a rising VCC. |
| 5 | BAT | power_out | Charge current output to the battery; the BAT pin absolute maximum is -0.3 V to 7.0 V and the recommended continuous charge current is 600 mA. |
| 6 | POK | output | Open-drain output indicating charge completion and power status; it is pulled low when charging is complete. |
| 7 | CHRG | output | Open-drain output indicating charge status; it is pulled low while charging and high-impedance in other states. |
| 8 | NC | unconnected | No-connect pin (空脚) with no internal function. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
