Broadcom's ACPL-W349 contains an AlGaAs LED, which is optically coupled to an integrated circuit with a power output stage. This optocoupler is ideally suited for driving SiC/GaN (silicon carbide/gallium nitride) MOSFETs and IGBTs used in power conversion applications. The high operating voltage range of the output stage provides the drive voltages required by gate controlled devices. The voltage and high peak output current supplied by this optocoupler make it ideally suited for direct driving SiC/GaN MOSFET and IGBT with ratings up to 1200 V/100 A.
