UCC21759-Q1 Single-Channel Isolated Gate Driver Texas Instruments UCC21759-Q1 Single-Channel Isolated Gate Driver is a galvanic isolated single-channel gate driver designed for SiC MOSFETs and IGBTs up to 990V DC operating voltage. The device comes with advanced protection features, best-in-class dynamic performance, and robustness. UCC21759-Q1 has up to ±10A peak source and sink current. The input side is isolated from the output side with SiO2 capacitive isolation technology, supporting up to 700VRMS working voltage with longer than 40 years isolation barrier life, 6kVPK surge immunity, as well as providing low part-to-part skew, and >, 150V/ns common-mode noise immunity (CMTI).
