Product details

Dual low-side driver with 4A peak drive for both N- and P-channel MOSFETs

The driver operates from a 4.5V to 15V supply, making it compatible with 5V and 12V logic rails without an extra regulator. The 8-HVSSOP package includes an exposed thermal pad for improved heat dissipation in high-switching-frequency applications.

The 4A peak source and sink rating determines how fast the MOSFET gate capacitance charges and discharges. With 20ns rise and 15ns fall times, the UCC37324DGN can drive moderate gate charges at switching frequencies up to several hundred kilohertz while keeping crossover losses low.

It is ROHS3 compliant.

Frequently asked questions

Does UCC37324DGN have an exposed pad?

Yes, the 8-HVSSOP package includes an exposed thermal pad for heat sinking.

What is the closest equivalent or replacement for UCC37324DGN?

The LM5106MM/NOPB is a functionally similar half-bridge driver from Texas Instruments, but it drives N-channel MOSFETs only (not P-channel), has 1.2A switching current, and operates from -40°C to 125°C. Verify pin compatibility and drive requirements before substituting.

What gate types does UCC37324DGN drive?

It drives both N-channel and P-channel MOSFETs, with independent non-inverting inputs per channel.
