Avago Technologies added the ACPL-332J and -331J series of high-speed IGBT optocouplers to its gate-drive optocoupler product family. The optocouplers are suited for power management applications, including isolated IGBT/power MOSFET gate drives, AC and brushless DC motor drives, industrial inverters and UPS.

The gate drivers improve precision and efficiency of motor inverters by featuring active miller clamp, integrated Vce desaturation detection, undervoltage lockout protection, built-in IGBT shutdown 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, the optocouplers possess common-mode rejection, which aids in reliable operation under noisy environments. The ACPL-332J and -331J are CSA approved.

The devices are available today. Pricing starts at $2.56 for 10,000 pieces.
