# FAN3227TMX

**onsemi** · Gate Drivers · SOIC-8

FAN3227TMX from onsemi, in a SOIC-8. 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 | ENA | input | Enable input for channel A; pulling the pin low disables driver A, and it has a TTL threshold (for both TTL and CMOS INx thresholds). |
| 2 | INA | input | Non-inverting input for channel A. |
| 3 | GND | power_in | Ground, the common reference for the input and output circuits. |
| 4 | INB | input | Non-inverting input for channel B. |
| 5 | OUTB | output | Gate drive output B, held low unless the required input is present and VDD is above the UVLO threshold. |
| 6 | VDD | power_in | Supply voltage pin that powers the IC. |
| 7 | OUTA | output | Gate drive output A, held low unless the required input is present and VDD is above the UVLO threshold. |
| 8 | ENB | input | Enable input for channel B; pulling the pin low disables driver B, and it has a TTL threshold (for both TTL and CMOS INx thresholds). |
