Avago Technologies is announcing the latest addition to its intelligent gate drive optocoupler product family. The new ACPL-332J and -331J series of high-speed IGBT optocouplers are said to be easy to implement in industrial inverter and power management applications, such as isolated IGBT/power MOSFET gate drives, AC and brushless DC motor drives, industrial inverters and uninterruptible power supplies.

When developing a reliable yet cost-effective motor control system, designers require optocouplers that provide more protection, efficiency and ability to operate in noisy environments. Avago's highly integrated ACPL-332J and -331J intelligent gate drivers improve precision and efficiency of motor inverters by featuring Active Miller Clamp, integrated Vce desaturation detection, under-voltage lockout protection, built-in IGBT shut down, and isolated open collector fault feedback. Active Miller clamping eliminates the need for a negative gate drive, saving negative power supply and PCB space. Additionally, Avago's new gate drive optocouplers enjoy a claimed industry-best CMR that ensures reliable operation under noisy environments.

The ACPL-332J and -331J are CSA approved. Approvals in the following widely accepted international safety standards are pending: UL1577 and IEC/EN/DIN EN 60747-5-2.

The products are available now through Avago's direct sales channel and worldwide distribution partners.
