3 Description

The UCC27516 and UCC27517 single-channel, high•

speed, low-side gate driver devices can effectively

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

current, UCC27516 and UCC27517 can source and

sink high peak-current pulses into capacitive loads

offering rail-to-rail drive capability and extremely small

propagation delay, typically 13 ns.

The UCC27516 and UCC27517 provides 4-A source,

4-A sink (symmetrical drive) peak-drive current

capability at VDD = 12 V.
