Introduction

The UCC21710 is a galvanically isolated single channel gate driver designed to drive up to 1700V SiC MOSFETs and IGBTs. It features advanced integrated protection, best-in-class dynamic performance, and robustness. UCC21710 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-KV RMS working voltage with longer than 40 years isolation barrier life, 12.8-kVₚₖ surge immunity, as well as providing low part-to-part skew, and >150V/ns common mode noise immunity (CMTI). The UCC21710 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.
