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.
●Features
●• Low-Cost Gate-Driver Device Offering Superior
● Replacement of NPN and PNP Discrete Solutions
