The UCC21710-Q1 is a galvanic isolated single channel gate drivers designed for up to 1700V SiC MOSFETs and IGBTs with advanced protection features, best-in-class dynamic performance and robustness. UCC21710-Q1 has up to ±10-A peak source and sink current.

The input side is isolated from the output side with SiO2 capacitive 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, >150V/ns common mode noise immunity (CMTI).

The UCC21710-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, 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.
