Product details

It operates from a 4V to 15V supply rail and delivers a typical 20ns rise time and 15ns fall time into the gate load — fast enough to keep switching losses in check for medium-frequency power stages like synchronous buck converters, push-pull converters, and motor-drive low-side FETs. The two channels are independent and non-inverting, so you can parallel them for higher peak current or drive two separate devices with independent control signals.

The 4A source and 4A sink peak rating determines how fast the gate capacitance charges and discharges, which directly sets the switching transition time.

Supply range and logic thresholds

The 4V to 15V supply range covers 5V and 12V bias rails common in industrial control and automotive systems. The logic input thresholds are 1V (VIL) and 2V (VIH).

Package and thermal management

The exposed pad is also the ground return for the output stage — keep the PCB trace short and wide to the source of the low-side FET.

Frequently asked questions

What is the UCC27424DGNR used for?

It is a dual low-side gate driver used to drive N-channel and P-channel MOSFETs in applications such as synchronous buck converters, push-pull converters, motor-drive low-side FETs, and other power stages requiring 4A peak gate drive with fast 20ns rise and 15ns fall times.

What is the difference between UCC27424DGNR and UCC27424DGN?

The UCC27424DGNR and UCC27424DGN share the same electrical specifications — both are dual low-side gate drivers with 4A peak source/sink, 20ns/15ns rise/fall, and the same 8-HVSSOP package. The difference is the packaging format: DGNR is supplied in Tape & Reel (TR), while DGN is typically supplied in tubes or other non-reel packaging. The die and performance are identical.

What are the alternatives to UCC27424DGNR?

A functional alternative is the LM5106MM/NOPB, which is a half-bridge gate driver for N-channel MOSFETs with 1.2A peak drive and 15ns/10ns rise/fall. However, the LM5106 is a half-bridge driver with synchronous channel type, not a dual low-side driver, and has lower peak current. It is not a direct pin-compatible replacement — the UCC27424DGNR is a low-side driver with independent channels, while the LM5106 integrates high-side and low-side drive for a half-bridge topology.
