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.
