FM4063 from Shenzhen Fuman, 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 | Listed in the pin table as an empty pin (空脚) with no function, so it is not connected. |
| 2 | PROG | passive | Sets charge current through a 1% resistor from PROG to GND (IBAT = 1200/RPROG); PROG is held at 1 V in constant-current mode, and charge current is 0 if no resistor is fitted. |
| 3 | GND | power_in | Power ground for the charger. |
| 4 | VCC | power_in | Positive input supply operating from 4.5 V to 5.5 V, to be bypassed with at least 1 µF (22 µF where the input supply may be shorted); input over-voltage protection trips above about 6.0 V typ., and the absolute maximum rating is 30 V. |
| 5 | BAT | power_out | Charge current output to the battery that regulates the float voltage to 4.25 V (stated accuracy ±1%); the internal resistor divider that sets float voltage is disconnected in shutdown mode. |
| 6 | CHRGT | output | Open-drain full-charge indicator that is pulled low by an internal switch when charging is complete and is high-impedance otherwise, so an external pull-up is needed for MCU sensing. |
| 7 | CHRG | output | Open-drain charge-status indicator that is pulled low while charging and is high-impedance otherwise; it can sink up to 10 mA and needs an external pull-up for MCU sensing. |
| 8 | NC | unconnected | Listed in the pin table as an empty pin (空脚) with no function, so it is not connected. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
