MIC4424YM-TR from Microchip, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	NC	unconnected	No internal connection. Leave floating or tie to any convenient node.
2	INA	input	Control input for channel A. TTL-compatible logic input; VIH ≥ 2.4V, VIL ≤ 0.8V. Withstands input swing down to −5V. Ground unused inputs.
3	GND	power_in	Device ground return. Common ground for logic input and output stage.
4	INB	input	Control input for channel B. TTL-compatible logic input; VIH ≥ 2.4V, VIL ≤ 0.8V. Withstands input swing down to −5V. Ground unused inputs.
5	OUTB	output	Channel B non-inverting MOSFET gate driver output. 3A peak, rail-to-rail swing within 25 mV of VS or GND, ~3.5Ω typical output impedance.
6	VS	power_in	Positive supply input, 4.5V to 18V (22V absolute max). Bypass locally with 0.1µF ceramic in parallel with 4.7µF bulk near the device.
7	OUTA	output	Channel A non-inverting MOSFET gate driver output. 3A peak, rail-to-rail swing within 25 mV of VS or GND, ~3.5Ω typical output impedance.
8	NC	unconnected	No internal connection. Leave floating or tie to any convenient node.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`mic4424ym-tr.step`	122 KB	You want the bare part, or you mark your own boards.
`mic4424ym-tr-etched.step`	1.9 MB	You want the part with `MIC4424YM-TR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 497 faces against 147 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
