UCC27423DGNR from Texas Instruments, in a HVSSOP-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 | ENBA | input | Enable input for driver A with logic compatible threshold and hysteresis; internally pulled up to VDD with 100 kΩ resistor for active high operation; output state when disabled will be low regardless of input state. |
| 2 | INA | input | Input A signal for the A driver with logic compatible threshold and hysteresis; must be tied to either VDD or GND if not used, must not be left floating. |
| 3 | GND | power_in | Common ground connected very closely to the source of the power MOSFET which the driver is driving. |
| 4 | INB | input | Input B signal for the B driver with logic compatible threshold and hysteresis; must be tied to either VDD or GND if not used, must not be left floating. |
| 5 | OUTB | output | Driver output B capable of providing 4A drive current to the gate of a power MOSFET. |
| 6 | VDD | power_in | Supply voltage and power input connection for this device. |
| 7 | OUTA | output | Driver output A capable of providing 4A drive current to the gate of a power MOSFET. |
| 8 | ENBB | input | Enable input for driver B with logic compatible threshold and hysteresis; internally pulled up to VDD with 100 kΩ resistor for active high operation; output state when disabled will be low regardless of input state. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |

Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
