3 Description
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 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.
