2.2 Isolated Gate Driver

The TIDA-020030 reference design has two UCC21732-Q1 galvanic isolated single-channel gate drivers designed for up to 1700-V SiC MOSFETs and IGBTs with advanced protection features. The UCC21732-Q1 gate drivers have up to ±10-A drive strength, support up to 1.5-kVRMS working voltage, and 12.8-kVPK surge immunity with longer than 40 years of isolation barrier life. The UCC21732-Q1 gate drivers are used to drive the high and low side of the IGBT module, although this test uses only the high-side driver.
