**Texas Instruments** · Gate Drivers · SOIC-8

UCC37324DR from Texas Instruments, in a SOIC-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 | N/C | unconnected | No internal connection. |
| 2 | INA | input | Input signal for channel A driver with TTL/CMOS compatible logic thresholds and hysteresis; if unused, must be tied to either VDD or GND. |
| 3 | GND | power_in | Common ground connected very closely to the source of the power MOSFET being driven. |
| 4 | INB | input | Input signal for channel B driver with TTL/CMOS compatible logic thresholds and hysteresis; if unused, must be tied to either VDD or GND. |
| 5 | OUTB | output | Driver output B capable of sourcing and sinking ±4-A peak drive current to power MOSFET gate. |
| 6 | VDD | power_in | Supply voltage input for device operation; recommended range 4.5 V to 15 V. |
| 7 | OUTA | output | Driver output A capable of sourcing and sinking ±4-A peak drive current to power MOSFET gate. |
| 8 | N/C | unconnected | No internal connection. |
