GX4054 from GUOXIN JIAPIN SEMICONDUCTOR, in a SOT-23-5L. 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 | CHRG | output | Open-drain charge status output that is pulled low by an internal N-channel MOSFET during a charge cycle and goes high-impedance when the cycle ends, and it can sink up to 10 mA to drive an LED. |
| 2 | GND | power_in | Ground pin for the charger. |
| 3 | BAT | power_out | Charge current output to the battery that regulates the final float voltage to 4.2 V (±1%) through an internal precision resistor divider, which is disconnected in shutdown mode. |
| 4 | VCC | power_in | Positive input supply that must stay within 4.5 V to 7.0 V (absolute maximum -0.3 V to 8 V) and should be bypassed with at least a 1 µF capacitor. |
| 5 | PROG | passive | Charge current program pin: an external resistor to ground sets the charge current via IBAT = (VPROG/RPROG) × 1150, with VPROG about 1.0 V in constant-current mode and a PROG pin current absolute maximum of 700 µA. |
