Avago Technologies’ ACPL-332J and -331J series of intelligent gate drive optocouplers feature a high common-mode rejection, which ensures reliable operation under noisy environments. These high-speed IGBT optocouplers suit industrial inverter and power management applications, such as isolated IGBT/power MOSFET gate drives, ac and brushles-dc motor drives, industrial inverters and UPSs.
The integrated gate drivers improve precision and efficiency of motor inverters by featuring Active Miller Clamp, integrated VCE desaturation detection, UVLO, built-in IGBT shut down, and isolated open-collector fault feedback. Active Miller clamping also eliminates the need for a negative gate drive. The ACPL-332J is priced at $3.24, and the ACPL-331J is priced at $2.56, both in 10,000-piece quantities.
