LOWPOWER · Battery Management ICs · SOT-23-5
LP4063B5F 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 | CHRG | output | Open-drain charge status output pulled low by an internal NMOS while charging, and pulled high by an external resistor when the charge cycle is complete (about 5mA strong pull-down, 0.1V max output low at 5mA). |
| 2 | GND | power_in | Connection to system ground. |
| 3 | BAT | passive | Connection to the battery; needs a 10µF tantalum capacitor for stability with no battery attached, or only a 1µF ceramic capacitor when a battery is attached. |
| 4 | VIN | power_in | Input power source connected to a wall adapter; operating range 4.4V to 6.5V, with a 3.3V typical undervoltage lockout, a 7V overvoltage threshold and a 28V absolute maximum. |
| 5 | ISET | passive | Charge current program pin; the charge current is set by a 1% resistor (RISET) to ground, with a recommended range of 1.3kΩ to 3.3kΩ and about 1V on the pin in current mode. |
