# UCC37323P

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

UCC37323P from Texas Instruments, in a PDIP-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 | N/C | unconnected | No Internal Connection |
| 2 | INA | input | Input signal of the A driver with logic compatible threshold and hysteresis; if not used, must be tied to either VDD or GND, must not be left floating. |
| 3 | GND | power_in | Common ground; this ground should be connected very closely to the source of the power MOSFET which the driver is driving. |
| 4 | INB | input | Input signal of the B driver with logic compatible threshold and hysteresis; if not used, must be tied to either VDD or GND, must not be left floating. |
| 5 | OUTB | output | Driver output B capable of providing 4-A drive current to the gate of a power MOSFET. |
| 6 | VDD | power_in | Supply voltage and the power input connection for this device. |
| 7 | OUTA | output | Driver output A capable of providing 4-A drive current to the gate of a power MOSFET. |
| 8 | N/C | unconnected | No Internal Connection |
