High CMR Intelligent Power Module Optocoupler
Product Announcement from Avago Technologies
Reverse Logic High CMR Intelligent Power Module and Gate Drive Interface Optocoupler.
The ACPL-M483 High CMR Intelligent Power Module is a high speed optocoupler containing a GaAsP LED and photo detector with built-in Schmitt trigger to provide logic-compatible waveforms, eliminating the need for additional wave shaping. The totem pole output eliminates the need for a pull up resistor and allows for direct drive of Intelligent Power Module or as a gate driver. Minimized propagation delay difference between devices makes these High CMR Intelligent Power Module optocouplers an excellent solution for improving inverter efficiency through reduced switching dead time. The ACPL-M483 has an increased common mode transient immunity of 30kV/µs minimum at VCM = 1000V guaranteed over wide operating temperature range
