3 Description
The UCCx8C5x family are high-performance, currentmode
PWM controllers with low startup current.
The UCCx8C5x is an enhanced BiCMOS version
with pin-for-pin compatibility to the industry standard
UCCx8C4x family. With the VDD absolute maximum
rating extended from 20 V to 30 V for optimal
gate voltage design on 20-Vgs, 18-Vgs or 15-Vgs
SiC MOSFETs by the introduction of UCC28C56H/L,
UCC28C57H/L and UCC28C58/9, three new sets of
UVLO options allow SiC FET operating reliably while
avoiding thermal runaway. Existing UVLO options of
UCCx8C4x are maintained with improvements on
startup current, operating current and VDD absolute
maximum rating.
The UCC28C5x series is specified for operation
from –40°C to 125°C, and the UCC38C5x series is
specified for operation from 0°C to 85°C.
The table below compares the improvements from
UCCx8C5x to UCCx8C4x.
