LP4074B5F
LOWPOWER · Battery Management ICs · SOT-23-5
LP4074B5F from LOWPOWER, 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 | 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 completed. |
| 2 | GND | power_in | Ground reference pin for the charger. |
| 3 | BAT | power_out | Charge current output that supplies the battery and regulates the final float voltage to 4.2V. |
| 4 | VIN | power_in | Positive input supply voltage, specified for an adapter/USB voltage range of 4.5V to 6.5V with a 3.8V VIN undervoltage lockout threshold. |
| 5 | ISET | passive | Charge current program and monitor pin, programmed by a 1% resistor to ground; it servos to 1V in constant-current mode and IBAT = 1000/RISET. |
