The UCC21736-Q1 is a galvanic isolated singlechannel gate driver designed for SiC MOSFETs and IGBTs up to 2121-V DC operating voltage withadvanced protection features, best-in-class dynamic performance and robustness. UCC21736-Q1has up to ±10-A peak source and sink current.
The input side is isolated from the output side with SiO2capacitive isolation technology, supporting up to 1.5-kVRMS working voltage,12.8-kVPK surge immunity with longer than 40 years isolation barrier life,as well as providing low part-to-part skew, and >150V/ns common mode noise immunity(CMTI).
The UCC21736-Q1 includes thestate-of-art protection features, such as fast overcurrent and short circuit detection, shuntcurrent sensing support, fault reporting, active miller clamp, input and output side power supplyUVLO to optimize SiC and IGBT switching behavior and robustness. The ASC feature can be utilized toforce ON power switch during system failure events, further increasing the drivers versatility andsimplifying the system design effort, size and cost.
