TI UCC28C53DR

The UCCx8C5x family of devices are highperformance current-mode PWM controllers that can drive both Si and SiC MOSFETs in various applications. The UCCx8C5x family is a more efficient and robust version of the UCCx8C4x. The UCCx8C5x family has new UVLO thresholds that allow for reliable SiC MOSFET operation (UCC28C56 - 59), in addition to existing UVLO thresholds for continued Si MOSFET support (UCCx8C50 - 55). VDD absolute maximum voltage rating is extended from 20V to 30V 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. The UCCx8C5x family is offered in 8 - pin VSSOP (DGK), and 8 - pin SOIC (D) packages.
