Avago Technologies introduces three new gate drive optocouplers optimised for reliability and performance. As equipment manufacturers in industrial automation and data center power supply markets transition to developing more energy efficient products, Avago has engineered new optocouplers with industry’s high common mode rejection (CMR) ratio (40 kV/µs @VCM=1500V).
This key specification guarantees the reliable transfer of drive information at very high DC-link voltage and over fast switching operations. Short propagation delay, under voltage lockout (UVLO) and high-output driving current also improve motor inverter efficiency, motion precision and performance.
Avago’s ACPL-3130, ACPL-J313 and ACNW-3130 gate drive optocouplers are ideal for applications such as isolated IGBT/ MOSFET-gate drives for industrial motors, industrial inverters, switching power supplies (SPS) and uninterruptible power supplies. The optocouplers deliver 2.5A maximum peak output current and 2.0A minimum peak output current. Additionally, the products support a wide operating voltage range (15 to 30 volts) required by gate-controlled devices.
As part of Avago’s extensive range of high-performance, isolated, gate drive optocouplers, the ACPL-3130 contains a GaAs LED, while the ACPL-J313 and ACNW-3130 contain an AIGaAs LED. The new optocouplers have received approval in accordance with the following safety standards: UL (pending), CSA (pending) and IEC/EN/DIN EN 60747-5-2.
