FP6861C-C2AS5CTR from Fitipower Integrated Tech, 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 | EN | input | Active-low chip enable for the C2 variant (ordering code digit 2 = Active Low): pull low to enable the IC, pull high to shut it down, and do not let the pin float. |
| 2 | GND | power_in | Ground reference for the device. |
| 3 | VIN | power_in | Input power supply; the recommended operating supply range is 2.7 V to 5.5 V, with at least a 1 µF low-ESR ceramic capacitor from VIN to GND. |
| 4 | OC | output | Open-drain error flag output that goes low on current limit, short circuit or thermal shutdown; connect to VIN through a pull-up resistor. |
| 5 | VOUT | power_out | Switch output (MOSFET source) to the load; the switch is bidirectional when enabled and blocks reverse current from VOUT to VIN when disabled. |
