Analog Devices, Inc. (ADI) today introduced the ADuM4135 isolated IGBT gate driver to improve electric motor energy efficiency, reliability and system-control performance in industrial motor control applications. Incorporating ADI’s award-winning iCoupler® digital isolator technology, the ADuM4135 ensures safety and reliability through proven galvanic isolation in a single package while delivering the industry’s best combination of CMTI (common-mode transient immunity) at 100 kV/µs and propagation delay of 50 ns (typical).
