Product details

Dual 4A low-side driver for N- and P-channel gates

The inverting input logic means a logic-high on the input pulls the output low — confirm the polarity matches your PWM controller before layout.

Supply rail and temperature — what fits

The supply range spans 4 V to 15 V, covering 5 V logic rails and 12 V gate drive levels common in telecom rectifiers and industrial power supplies.

No official second source or successor is listed — dual-sourcing would require a parametric match from another vendor's low-side driver family.

Frequently asked questions

What is the difference between UCC27423DGNR and UCC27424?

The UCC27423DGNR has inverting inputs, while the UCC27424 has non-inverting inputs. Both are dual low-side drivers with 4A peak output and the same package options — the choice depends on whether your PWM controller output polarity is active-high or active-low.
