1. Description

The Broadcom® high-speed ACPL-P480-500E optocoupler contains a GaAsP LED, a photo detector, and a Schmitt trigger that eliminates the requirement for external waveform conditioning circuits. The totem pole output eliminates the need for a pull-up resistor and allows for a direct-drive Intelligent Power Module or gate drive. Propagation delay difference between devices has been minimized to maximize inverter efficiency through reduced switching dead time.

2. Features

    1. Performance specified for common IPM applications over industrial temperature range

    2. Short maximum propagation delays
