UCC37322DR 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 (4.5-15 V); must connect externally to pin 8 with 0.1-µF bypass capacitor to AGND. |
| 2 | IN | input | Logic input with TTL/CMOS-compatible threshold (VIN_H 1.6-2.5 V, VIN_L 0.8-1.5 V). |
| 3 | ENBL | input | Enable input, internally pulled high to VDD via 100-kΩ resistor (VEN_H 1.7-2.7 V, VEN_L 1.1-2 V); forces output low when disabled. |
| 4 | AGND | power_in | Analog ground for input stage; connect directly to PGND with single thick trace and place 0.1-µF bypass capacitor to VDD (pin 1). |
| 5 | PGND | power_in | Power ground for output stage; connect closely to power MOSFET source to minimize ringing from output switching di/dt. |
| 6 | OUT | output | Driver output (connect to pin 7); ±9-A peak drive current with output resistance 0.4-1.5 Ω. |
| 7 | OUT | output | Driver output (connect to pin 6); ±9-A peak drive current with output resistance 0.4-1.5 Ω. |
| 8 | VDD | power_in | Supply voltage input (4.5-15 V); must connect externally to pin 1 with 0.1-µF bypass capacitor to PGND. |
