UCC27322DR from Texas Instruments, in a SOIC-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 | VDD | power_in | Supply voltage input connection for the device, rated 4.5 V to 15 V, must be connected externally to Pin 8. |
| 2 | IN | input | Input signal of the driver with logic compatible threshold (VIN_H 1.6 V to 2.5 V, VIN_L 0.8 V to 1.5 V) and hysteresis. |
| 3 | ENBL | input | Enable input with logic compatible threshold and hysteresis, internally pulled up to VDD with 100-kΩ resistor for active high operation, controlling driver output enable/disable state. |
| 4 | AGND | power_in | Analog ground for input stage that must be connected to Pin 5 via single thick trace directly under the device, with 0.1-µF bypass capacitor to VDD (Pin 1). |
| 5 | PGND | power_in | Power ground for output stage that must be connected directly to the source of the power MOSFET and to Pin 4 via single thick trace, with 0.1-µF bypass capacitor to VDD (Pin 8). |
| 6 | OUT | output | Driver output capable of providing 9-A peak drive current to the gate of a power MOSFET, must be connected externally to Pin 7. |
| 7 | OUT | output | Driver output capable of providing 9-A peak drive current to the gate of a power MOSFET, must be connected externally to Pin 6. |
| 8 | VDD | power_in | Supply voltage input connection for the device, rated 4.5 V to 15 V, must be connected externally to Pin 1. |
