Broadcom's intelligent gate driven optocouplers ACPL-352J, ACPL-339J, ACPL-302J and ACPL-337J provide integrated IGBT protection and fault feedback. Gate driven optical couplers are widely used to provide enhanced insulation and to provide high gate voltages and currents to drive power switches such as IGBT or power MOSFET. Because of its simplicity, designers often need to add the following external discrete components to complete the drive and protection of the power switch

The Broadcom Smart Gate driven optocoupler integrates all of these discrete features into a single component to reduce the number of discrete components, PCB space, cost, and design cycle time. Smart gate driven optocouplers help protect expensive IGBTs from short or overcurrent, false outputs, and destroy high voltage transients. This improves the reliability of expensive power switches, reducing system failures and operating costs.
