**UMW** · Gate Drivers · SOT-23-5

FAN3111ESX from UMW, 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 | VDD | power_in | Bias supply input; the recommended supply range is 4.5 V to 25 V. |
| 2 | GND | power_in | Ground reference; all signals are referenced to this pin. |
| 3 | IN+ | input | Non-inverting CMOS logic input with thresholds referenced to VDD; recommended input voltage range is -10 V to 25 V. |
| 4 | IN- | input | Inverting CMOS logic input with thresholds referenced to VDD; recommended input voltage range is -10 V to 25 V. |
| 5 | OUT | output | Gate-drive output for the external N-channel MOSFET, rated for 2 A peak source and sink drive current. |
