SD8057T

SHOUDING · Battery Management ICs · TSOT-23-6

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.
