Gcore · Battery Management ICs · SOT-23-5
GC4054B from Gcore, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | CHRG | tri_state | Open-drain charge status output, pulled low during charging and forced to high-impedance state on charge completion or under-voltage lock condition. |
| 2 | GND | power_in | Ground reference. |
| 3 | BAT | power_out | Battery charging current output; supplies charging current and regulates float voltage to 4.2V with input voltage 4.25V to 6.5V at VCC. |
| 4 | VCC | power_in | Positive input power supply voltage 4.25V to 6.5V; requires bypass capacitor of at least 1µF. |
| 5 | PROG | input | Charge current programming and monitoring pin; connect 1% precision resistor to ground to set charging current (Ibat = 1000/Rprog mA) and to control shutdown mode. |
