3 Description

The UCC2753x single-channel, high-speed gate

drivers can effectively drive MOSFET and IGBT

power switches. Using a design that allows for a

source of up to 2.5 A and 5-A sink through

asymmetrical drive (split outputs), coupled with the

ability to support a negative turn-off bias, rail-to-rail

drive capability, extremely small propagation delay

(17 ns typical), the UCC2753x devices are ideal

solutions for MOSFET and IGBT power switches. The

UCC2753x family of devices can also support enable,

dual input, and inverting and non-inverting input

functionality. The split outputs and strong

asymmetrical drive boost the devices immunity

against parasitic Miller turn-on effect and can help

reduce ground debouncing.
