The UCC28C5x-Q1 family of devices are high performance current-mode PWM controllers which can be used to drive both Si and SiC MOSFETs in various applications. The UCC28C5x-Q1 family is a more efficient and robust version of the UCC28C4x-Q1.

The UCC28C5x-Q1 family has new UVLO thresholds that allow for reliable SiC MOSFET operation (UCC28C56-59-Q1), in addition to existing UVLO thresholds for continued Si MOSFET support (UCC28C50-55-Q1).

VDD absolute maximum voltage rating is extended from 20 V to 30 V for optimally driving the gate of 20-Vgs, 18-Vgs, or 15-Vgs SiC MOSFETs, while also allowing for the exclusion of an external LDO.
