Product details

4 A peak drive — what it buys you

The UCC27323D is a dual low-side gate driver from Texas Instruments, designed to drive N-channel and P-channel MOSFETs with a peak output current of 4 A source and 4 A sink per channel. The 20 ns rise and 15 ns fall times (typical) keep switching losses low in DC-DC converters, motor-drive stages, and synchronous rectifier circuits running up to several hundred kilohertz.

Supply rail and logic thresholds

Operating from 4.5 V to 15 V, the driver accepts common gate-drive rails — 5 V for logic-level MOSFETs, 12 V for standard power MOSFETs — without an external regulator.

Frequently asked questions

Can UCC27323D drive IGBTs?

Yes — the 4 A peak output and 20 ns rise / 15 ns fall times are sufficient for small to medium IGBTs in low-side switching applications, provided the gate charge does not exceed the driver's peak current capability at the target frequency.

What is the difference between UCC27323D and UCC27324?

The UCC27323D has inverting inputs; the UCC27324 has non-inverting inputs. Both are dual low-side drivers with the same 4 A peak output, supply range, and 8-SOIC package. The choice depends on the polarity of the PWM signal from the controller.
