Description
AI
The UCCx8C5x family of devices are high-performance 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 20 V to 30 V for optimally driving the gate of 20-V gs, 18-V gs, or 15-V gs 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.
