Introduction

HCPL-T251 contains a GaAsP LED optically coupled to an integrated circuit with a power output stage. This optocoupler is ideally suited for driving power IGBTs and MOSFETs used in motor control inverter applications. The high operating voltage range of the output stage provides the drive voltage required for gate-controlled devices. The voltage and current provided by this optocoupler make it well suited for directly driving small- to medium-power IGBTs.
