Product details

9A peak drive, inverting input, 8-SOIC

The UCC27321D: It drives both N-channel and P-channel MOSFETs, making it a flexible choice for synchronous rectifiers, DC-DC converters, and motor-drive stages where a single high-current gate-drive channel is needed.

The supply voltage range spans 4V to 15V, covering common bias rails from 5V to 12V without an external regulator. Logic input thresholds are 1.1V (VIL) and 2.7V (VIH), compatible with 3.3V and 5V logic families directly — no level-shifter needed between the controller and the driver.

Frequently asked questions

Is UCC27321D inverting or non-inverting?

The UCC27321D has an inverting input — the output goes high when the input is low.

Can UCC27321D drive N-channel and P-channel MOSFETs?

Yes, the UCC27321D is specified to drive both N-channel and P-channel MOSFETs, offering flexibility in half-bridge and synchronous rectifier designs.
