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).
