ACPL-W346 Gate Drive Optocoupler

Broadcom's 2.5 A output current, power and SiC MOSFET gate drive optocoupler

Image of Broadcom's ACPL-W346 Gate Drive OptocouplerBroadcom's ACPL-W346 is a high-speed 2.5 A gate drive optocoupler that contains an AlGaAs LED, which is optically coupled to an integrated circuit with a power output stage. This optocoupler is ideally suited for driving power and silicon carbide (SiC) MOSFETs used in inverter or AC-DC/DC-DC converter 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 MOSFETs at high frequency for high efficiency conversion. The ACPL-W346 has the highest insulation voltage of VIORM = 1140 VPEAK in the IEC/ EN/DIN EN 60747-5-5 and is UL1577 recognized with 5000 VRMS for 1 minute.
