Product details

4A source, 8A sink — asymmetric drive for fast turn-off

The UCC27512DRST is a single-channel low-side gate driver from Texas Instruments, designed to drive IGBTs and N-channel MOSFETs. Its peak output current is 4 A source and 8 A sink, meaning the gate is pulled down harder than it is pushed up — a deliberate asymmetry that speeds up the turn-off edge and reduces cross-conduction losses in half-bridge and synchronous-rectifier stages.

8 ns rise, 7 ns fall — switching-loss budget

These edge rates keep switching losses low in hard-switched topologies running at several hundred kilohertz. The input accepts both inverting and non-inverting signals, giving the designer polarity flexibility without an external inverter.

Frequently asked questions

Can UCC27512DRST drive MOSFETs?

Yes. The gate type is listed for both IGBT and N-channel MOSFET. The 4 A source / 8 A sink peak output is sufficient to drive medium-power MOSFETs in switch-mode power supplies, motor drives, and DC-DC converters up to several hundred kilohertz.

What is the typical application for UCC27512DRST?

Typical applications include low-side gate drive in switch-mode power supplies, DC-DC converters, motor-drive inverter stages, and synchronous rectifier circuits. The wide supply range and fast edge rates suit both 5 V and 12 V gate drive rails in industrial and automotive power stages.
