●3 Description
●The UCC27517A-Q1 single-channel high-speed low-side gate-driver device effectively drives MOSFET and IGBT power switches. With a design that inherently minimizes shoot-through current, the UCC27517A-Q1 sources and sinks high peak-current pulses into capacitive loads offering rail-to-rail drive capability and extremely small propagation delay typically 13 ns.
