SM5201 from HICHON, in a SOT-23-5. 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 pulls strongly low (about 10mA) during a charge cycle and is high impedance in undervoltage lockout or when charging is terminated; absolute maximum -0.3V to 10V, tie to ground if unused. |
| 2 | GND | power_in | Ground. |
| 3 | BAT | power_out | Charge current output to the battery, up to 500mA, regulated to a 4.2V float voltage (±1%), with absolute maximum -0.3V to 7V. |
| 4 | VCC | power_in | Positive input supply voltage with 4.0V to 6.5V normal operating range and absolute maximum -0.3V to 9V, with undervoltage lockout threshold of 3.6V typical. |
| 5 | PROG | bidirectional | Charge current program, charge current monitor and shutdown pin; a resistor to ground sets charge current as RPROG = 1000/IBAT, PROG floating enters shutdown, absolute maximum -0.3V to VCC+0.3V. |
