Avago Technologies Delivers Gate Drive Optocouplers with Industry’s Highest Common Mode Rejection (CMR) Ratio

Avago Technologies Delivers Gate Drive Optocouplers with Industry's Highest Common Mode Rejection (CMR) Ratio

Avago Technologies has introduced three new gate drive optocouplers optimized for reliability and performance. As equipment manufacturers in industrial automation and data center power supply markets transition to developing more energy efficient products which require fast switching operation, Avago has engineered new optocouplers with the industry’s highest common mode rejection (CMR) ratio (40 kV/µs @VCM=1500V).

New Optocouplers Significantly Improve Reliability and Performance

CMR is the maximum slew rate of common mode voltage (VCM) which can be sustained, keeping the output in the correct logic state. CMR failure results in glitching on the output as either a positive or negative pulse. This key specification guarantees the reliable transfer of drive information at very high DC-link voltage and over fast switching operations.

Avago’s new ACPL-3130, ACPL-J313 and ACNW3130 gate drive optocouplers are ideal for applications such as isolated IGBT/ MOSFET-gate drives for industrial inverters, switching power supplies (SPS) and uninterruptible power supplies. The optocouplers deliver 2.5 A maximum peak output current. Additionally, the products support a wide operating voltage range (15 to 30 volts) required by gate-controlled devices.
