Si825xx Isolated Gate Drivers

Our Si825xx automotive products are robust gate drivers for Silicon, GaN or SiC based power converter systems such as SMPS or inverters. This family has upgraded features such as a high voltage input (logic side) VDD supply pin that supports up to 20 V. It has a robust 30 V driver VDD capability, low latency for tighter loop control, high CMTI of 125 kV/µs, -5 V voltage withstand on output pins and over-temperature protection. These also feature a driver boost stage which provides an increased current drive capability during the Miller plateau region for faster turn-on times. Based on our proprietary CMOS capacitive isolation technology, these products deliver superior performance in terms of robust isolation rating to enable driving state-of-the-art GaN or SiC FETs for maximizing system efficiency while ensuring safety with features such as UVLO protection and dead-time programmability.
