The UCC21739-Q1 is a galvanic isolated single channel gate drivers designed for SiC MOSFETs and IGBTs up to 900V DC operating voltage with advanced protection features, best-in-class dynamic performance and robustness. UCC21739-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 636VRMS working voltage, 6kVPK surge immunity basic isolation 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 UCC21739-Q1 includes the state-of-art protection features, such as fast overcurrent and short circuit detection, shunt current sensing support, fault reporting, active miller clamp, and input and output side power supply UVLO to optimize SiC and IGBT switching behavior and robustness. The isolated analog to PWM sensor can be utilized for easier temperature or voltage sensing, further increasing the drivers versatility and simplifying the system design effort, size and cost.
