# UCC27322DGNR

**Texas Instruments** · Gate Drivers · MSOP-8-EP

UCC27322DGNR from Texas Instruments, in a MSOP-8-EP. 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 power input; must be connected externally to pin 8; operating range 4.5 V to 15 V. |
| 2 | IN | input | Input signal of the driver which has logic compatible threshold and hysteresis. |
| 3 | ENBL | input | Enable input for the driver with logic compatible threshold and hysteresis; internally pulled up to VDD with 100 kΩ resistor for active high operation; output state is low when device is disabled regardless of input state. |
| 4 | AGND | power_in | Analog ground connected to PGND by single thick trace directly under device; requires 0.1-µF bypass capacitor between VDD (pin 1) and AGND; control circuit ground must be common with AGND. |
| 5 | PGND | power_in | Common ground for output stage connected very closely to source of power MOSFET; grounds separated to minimize ringing effects from output switching di/dt; requires low ESR, low ESL 0.1-µF capacitor between VDD (pin 8) and PGND. |
| 6 | OUT | output | Driver output that must be connected together externally to pin 7; capable of providing 9 A peak drive current to power MOSFET gate. |
| 7 | OUT | output | Driver output that must be connected together externally to pin 6; capable of providing 9 A peak drive current to power MOSFET gate. |
| 8 | VDD | power_in | Supply voltage power input; must be connected externally to pin 1; operating range 4.5 V to 15 V. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
