Isolated Gate Drivers

Analog Devices’ isolated gate driver portfolio offers designers performance and reliability advantages over designs utilizing optocouplers or pulse transformers. Utilizing ADI’s proven iCoupler® technology, the isolated gate driver family offers the advantage of a maximum propagation delay of 50 ns, less than 5 ns channel-to-channel matching, a 50-year lifetime for 400 V rms working voltage and galvanic isolation in a single package.
