LP4061B6F from LOWPOWER, 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 | STAT1 | output | Open-drain charge status output that is pulled low by an internal N-channel MOSFET while the battery is charging and pulled high when the charge cycle is complete. |
| 2 | GND | power_in | Ground reference for the charger. |
| 3 | BAT | power_out | Charge current output that delivers charge current to the battery and regulates the final float voltage to 4.2V, disconnected in shutdown mode. |
| 4 | VCC | power_in | Positive input supply that powers the charger; VCC can range from 4.35V to 6.5V and should be bypassed with at least a 1µF capacitor. |
| 5 | STAT2 | output | Open-drain charge status output that is pulled high by an internal N-channel MOSFET while the battery is charging and pulled low when the charge cycle is complete. |
| 6 | PROG | bidirectional | Charge current program, charge current monitor and shutdown pin, where a 1% resistor to ground sets the charge current and floating the pin shuts the charger down. |
