Overview
The UCC5350MCD, manufactured by Texas Instruments, is a high-performance, single-channel isolated gate driver designed for driving MOSFETs, IGBTs, SiC MOSFETs, and GaN FETs. This component is part of the UCC53x0 series, which offers split outputs to independently control rise and fall times. The UCC5350MCD is particularly suited for motor drives and industrial power applications, providing enhanced performance over traditional optocouplers with lower part-to-part variation, reduced propagation delay, higher operating temperatures, and improved common-mode transient immunity (CMTI).
