3 Description

The UCC21717-Q1 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. UCC21717-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, and >150-V/ns

common mode noise immunity (CMTI).

The UCC21717-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.
