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).
