UCC27624DR from Texas Instruments, 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	ENA	input	Enable input for Channel A. Biasing ENA LOW disables Channel A output regardless of INA state; pulling ENA HIGH enables Channel A output. If floating, Channel A is enabled by default via an internal ~200 kΩ pullup resistor. Recommended to tie to VDD if unused. Threshold: VENx_H=2V typ, VENx_L=1V typ, hysteresis ~1V.
2	INA	input	Non-inverting input to Channel A. OUTA is held LOW if INA is unbiased or floating due to an internal ~120 kΩ pulldown resistor. Connect to GND if unused. Input high threshold VINx_H=2V typ, low threshold VINx_L=1V typ, capable of handling -10V.
3	GND	power_in	Device ground. All signals are referenced to this pin.
4	INB	input	Non-inverting input to Channel B. OUTB is held LOW if INB is unbiased or floating due to an internal ~120 kΩ pulldown resistor. Connect to GND if unused. Same thresholds as INA (VINx_H=2V typ, VINx_L=1V typ), capable of handling -10V.
5	OUTB	output	Channel B gate driver output. 5A peak source/sink current, low-side push-pull output. Pullup RoH=5Ω typ (PMOS DC), pulldown RoL=0.6Ω typ. Output swings from GND to VDD.
6	VDD	power_in	Bias supply input. Recommended operating range 4.5V to 26V (absolute max 30V). UVLO rising ~4.1V, falling ~3.8V, 0.3V hysteresis. Bypass with two ceramic capacitors (typically ≥1 µF and 0.1 µF) referenced to GND.
7	OUTA	output	Channel A gate driver output. 5A peak source/sink current, low-side push-pull output. Pullup RoH=5Ω typ (PMOS DC), pulldown RoL=0.6Ω typ. Output swings from GND to VDD.
8	ENB	input	Enable input for Channel B. Biasing ENB LOW disables Channel B output regardless of INB state; pulling ENB HIGH enables Channel B output. If floating, Channel B is enabled by default via an internal ~200 kΩ pullup resistor. Recommended to tie to VDD if unused.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`ucc27624dr.step`	122 KB	You want the bare part, or you mark your own boards.
`ucc27624dr-etched.step`	2.2 MB	You want the part with `UCC27624DR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 531 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.
