Product details

4A gate drive for fast switching of N- and P-channel MOSFETs

The UCC27323DGN: With typical rise and fall times of 20ns and 15ns respectively, the driver minimizes switching losses and dead-time requirements in hard-switched topologies.

Supply range and logic thresholds

The 4.5V to 15V supply range covers common bias rails from 5V logic supplies up to 12V gate drive rails, so the same part can be used across a 5V or 12V system without a separate regulator.

Wide temperature range and package thermal management

The 8-HVSSOP package with exposed pad (3.00mm width) requires a thermal land pattern on the PCB to conduct heat from the die into the board copper — the datasheet layout recommendation should be followed for full current capability at high ambient.

ROHS3 compliant, which means it meets the latest EU restriction-of-hazardous-substances directive for lead-free soldering processes.

Frequently asked questions

What is the closest functional second-source to UCC27323DGN?

The closest functional peer is the UCC27423D, which shares the same pinout, inverting inputs, independent channels, and 4A peak drive strength. For most industrial applications the UCC27423D is a drop-in replacement; for extended-temperature designs the UCC27323DGN is the correct choice.

What gate types does the UCC27323DGN support?

The driver is specified for both N-channel and P-channel MOSFETs. The inverting input configuration means the output is the logical inverse of the input pin — useful when the controller PWM polarity needs to be flipped for the power stage topology.
