SD8067B from SHOUDING, in a SOT-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 that is pulled low while the charger is charging the battery and is high-impedance otherwise; 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 (4.2V for the B version); battery leakage falls below 1µA in shutdown. |
| 4 | VCC | power_in | Positive input supply voltage, 4V to 8V, to be bypassed with at least a 10µF capacitor; charger enters shutdown when VCC falls within 30mV of the BAT voltage. |
| 5 | STDBY | output | Open-drain battery charge-complete indicator that is pulled low when charging is complete and high-impedance otherwise. |
| 6 | PROG | input | Charge current program, charge current monitor and shutdown pin; a 1% resistor RPROG to ground sets the charge current, the pin is held at 1V in constant-current mode, and floating it (pulled up by 0.2µA to the 2.7V shutdown threshold) shuts down the charger. |
