MIC94090YC6-TR from Microchip Tech, in a SC-70-6. 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 | VOUT | power_out | Drain of the P-Channel MOSFET, which is the switched output of the load switch. |
| 2 | GND | power_in | Ground: connect to electrical ground. |
| 3 | NC | unconnected | No internal connection; a signal or voltage applied to this pin will have no effect on device operation. |
| 4 | VIN | power_in | Source of the P-Channel MOSFET; operating input voltage range is 1.7V to 5.5V. |
| 5 | GND | power_in | Ground: connect to electrical ground (second ground pin, same function as pin 2). |
| 6 | EN | input | Active-high CMOS-compatible enable input for the switch, with an internal 2MΩ pull-down to GND so the output is off if the pin is left floating. |
