Texas Instruments UCC27517 High-Speed, Low-Side Gate Driver

TI UCC27517 High-Speed, Low-Side Gate Driver

Texas Instruments UCC27517 high-speed, low-side gate driver is capable of effectively driving MOSFET and IGBT power switches. TI UCC27517 uses a design that inherently minimizes shoot-through current, making it capable of sourcing and sinking high, peak-current pulses into capacitive loads that offer rail-to-rail drive capability and extremely small propagation delay (typically 13ns). UCC27517 provides 4A source, 4A sink (symmetrical drive) peak-drive current capability at VDD = 12V. This TI high-speed, low-side gate driver operates over a wide VDD range of 4.5V to 18V and wide temperature range of -40°C to 140°C. It is ideal for use in switch-mode power supplies, DC-to-DC converters, and more.

Features
