User's Guide
Using the UCC21520EVM-286, UCC20520EVM-286,
UCC21521CEVM-286, and UCC21530EVM-286
UCC2x5xxEVM-286 evaluation modules are designed for evaluation of TI's 5.7-kV
gate driver family with 4-A source and 6-A sink peak current for driving Si MOSFETs, IGBTs and
WBG devices such as SiC and GaN transistors. This user's guide covers the UCC21520EVM-286,
UCC20520EVM-286, UCC21521CEVM-286, and UCC21530EVM-286 used to evaluate the UCC21520DW,
UCC20520DW, UCC21521CDW, and UCC21530DWK, respectively. To evaluate other Iso-Drivers in the
UCC2x5xx family, TI recommends that the user read the data sheet thoroughly before switching the part in
the EVMs covered by this user guide. In this user guide, the UCC21520EVM-286 evaluation module is shown
as the primary example, and the key differences between the UCC21520EVM-286 and the UCC20520EVM-286,
UCC21521CEVM-286, and UCC21530EVM-286 will be highlighted accordingly.
