SD8057T from SHOUDING, in a TSOT-23-6. 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 pulled low while the charger is charging the battery, otherwise high impedance; can sink up to 10mA to drive an LED. |
| 2 | GND | power_in | Ground. |
| 3 | BAT | power_out | Charge current output that supplies charge current to the battery and regulates the final float voltage to 4.2V. |
| 4 | VCC | power_in | Positive input supply voltage, 4V to 9V, to be bypassed with at least a 1uF capacitor; the charger enters shutdown when VCC falls within 30mV of the BAT voltage. |
| 5 | STDBY | output | Open-drain battery charge-complete indicator pulled low when charging is complete, otherwise high impedance. |
| 6 | PROG | input | Charge current program, charge current monitor and shutdown pin; a 1% RPROG to ground sets the charge current and the pin is held at 1V in constant-current mode, with shutdown when floated and pulled up to the 2.7V threshold. |
