# UCC27322QDRQ1

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

UCC27322QDRQ1 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 and power input; pins 1 and 8 must be connected together externally, and the recommended VDD range is 4.5 V to 15 V. |
| 2 | IN | input | Driver input with logic-compatible threshold and hysteresis; for the UCC27322-Q1 this input is noninverting (the datasheet text prints the part as UCC37322-Q1 in this sentence). |
| 3 | ENBL | input | Enable input with logic-compatible threshold and hysteresis that is internally pulled up to VDD for active-high operation, and the output is low when the device is disabled regardless of the IN state. |
| 4 | AGND | power_in | Control-circuit ground that must be joined to PGND by a single thick trace directly under the device, with a low ESR, low ESL 0.1 µF capacitor between VDD (pin 1) and AGND. |
| 5 | PGND | power_in | Common ground for the output stage that must be connected very close to the source of the driven power MOSFET, with a low ESR, low ESL 0.1 µF capacitor between VDD (pin 8) and PGND. |
| 6 | OUT | output | Driver output that must be connected externally to pin 7, and the output stage can provide 9-A peak drive current to a power MOSFET gate. |
| 7 | OUT | output | Driver output that must be connected externally to pin 6, and the output stage can provide 9-A peak drive current to a power MOSFET gate. |
| 8 | VDD | power_in | Supply voltage and power input; pins 1 and 8 must be connected together externally, and the recommended VDD range is 4.5 V to 15 V. |
