UCC27425DGNR from Texas Instruments, in a MSOP-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	ENBA	input	Enable input for channel A. Active-high logic; OUTA is held low when ENBA is low or left floating (internal pull-down). TTL/CMOS compatible thresholds referenced to GND.
2	INA	input	Non-inverting logic input for channel A. TTL/CMOS compatible with hysteresis; drives OUTA in phase. Referenced to GND.
3	GND	power_in	Device ground return. Common reference for logic inputs, enables, VDD bypass, and gate-drive output return currents. Tie to the thermal PowerPAD for optimal thermal performance.
4	INB	input	Non-inverting logic input for channel B. TTL/CMOS compatible with hysteresis; drives OUTB in phase. Referenced to GND.
5	ENBB	input	Enable input for channel B. Active-high logic; OUTB is held low when ENBB is low or left floating (internal pull-down). TTL/CMOS compatible thresholds referenced to GND.
6	OUTB	output	Gate-drive output for channel B. 4-A peak source/sink current, rail-to-rail swing between GND and VDD, capable of driving high-capacitance MOSFET gates. Place bypass capacitance close to VDD/GND.
7	VDD	power_in	Bias supply input, 4 V to 15 V recommended (18 V absolute max). Bypass locally with a low-ESR ceramic capacitor (typically 1 uF or larger in parallel with a bulk capacitor) referenced to GND to supply peak gate-drive currents.
8	OUTA	output	Gate-drive output for channel A. 4-A peak source/sink current, rail-to-rail swing between GND and VDD, capable of driving high-capacitance MOSFET gates. Place bypass capacitance close to VDD/GND.
9	PowerPAD	power_in	Exposed thermal pad on the underside of the DGN package. Must be soldered to the PCB ground plane for proper thermal dissipation; electrically connected to GND (pin 3).
