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...
