Broadcom ACPL-H342/ACPL-K342 IGBT Gate Drive Optocoupler

Product Overview

The Broadcom ACPL-H342/ACPL-K342 is an optically isolated power output stage designed for driving power IGBTs and MOSFETs in motor control inverter applications. It features an integrated AlGaAs LED coupled to an IC with a power output stage, providing high operating voltage and peak output current suitable for direct driving IGBTs up to 1200V/150A. Key advantages include an active Miller clamp, rail-to-rail output voltage, fast propagation delay for minimal dead time, and under-voltage lock-out (UVLO) protection. This optocoupler enhances system reliability and performance in demanding industrial environments by simplifying controller design and eliminating the need for external circuitry.
