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.
