Optocouplers Demonstrate Fault Protection
Exhibiting fault protection, Avago Technologies’ ACPL-333J and ACPL-330J Series IGBT optocouplers integrate Vce desaturation detection, under voltage lockout protection, soft shut down, isolated fault feedback and automatic fault reset. The SO-16-packaged devices offer Active Miller clamping to eliminate the need for a negative gate drive, and meet minimum 8 mm creepage and clearance requirements. The CSA-, UL1577- and IEC/EN/DIN EN 60747-5-2-approved ACPL-333J yields 2.5 A output current, and the ACPL-330J yields 1.5 A output current. The optocouplers are suitable for 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. Pricing in 10,000 quantities is $3.38 each for the ACPL-333J and $2.81 each for the ACPL-330J.
