Description

The UCC27516 and UCC27517 single-channel, high-speed, low-side gate driver devices can effectivelydrive MOSFET and IGBT power switches. Using adesignthat inherently minimizes shoot-throughcurrent, UCC27516 and UCC27517 can source andsink high peak-current pulses into capacitive loadsoffering rail-to-rail drive capability and extremely smallpropagation delay, typically 13 ns.The UCC27516 and UCC27517 provides 4-A source4-A sink (symmetrical drive) peak-drive currentcapability at VDD = 12 V.

Applications

Switched-Mode Power Supplies

DC-DC Converters

Companion Gate-Driver Devices for Digital-PowerControllers

Solar Power, Motor Control, UPS

Gate Driver for Emerging Wide Band-Gap PowerDevices (such as GaN)
