UCC21710中文资料适用于 IGBT/SiC MOSFET、具有 OC 检测和内部钳位的 5.7kVrms ±10A 单通道隔离式栅极驱动器数据手册TI规格书

描述 Description

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-kVRMS 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.
