FAN3224TMX 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; pull LOW to inhibit driver A, and it has TTL thresholds for both TTL and CMOS INx thresholds. |
| 2 | INA | input | Input to channel A (non-inverting for FAN3224), driving OUTA. |
| 3 | GND | power_in | Ground, the common ground reference for input and output circuits. |
| 4 | INB | input | Input to channel B (non-inverting for FAN3224), driving OUTB. |
| 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 that provides power to the IC, with an operating range of 4.5 V to 18 V. |
| 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; pull LOW to inhibit driver B, and it has TTL thresholds for both TTL and CMOS INx thresholds. |
