UCC27516DRSR

单通道高速，低侧栅极驱动器 Single Channel High-Speed, Low-Side Gate Driver

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.
