3 Description

The UCC27511 and UCC27512 single-channel, high•

speed, low-side gate-driver device can effectively

drive MOSFET and IGBT power switches. Using a design that inherently minimizes shoot-through

current, UCC27511 and UCC27512 are capable of

sourcing and sinking high peak-current pulses into

capacitive loads offering rail-to-rail drive capability

and extremely small propagation delay, typically 13

ns.
