FAN3224TMX

onsemi · Gate Drivers · SOIC-8

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.

Materials and finish

As the datasheet states them (page.json metadata.appearance; the 3D model's colours follow it).

Part Material Colour / plating Datasheet says Page
contacts copper SOIC-8 package, the board reference is defined as the PCB copper adjacent to pin 6. 3

CAD (KiCad official)

  • Symbol: FAN3224TMX
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: fan3224tmx-etched.step / fan3224tmx-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); fan3224tmx.step / fan3224tmx.glb are the bare package body.
