Description

The high-speed ACPL-P481/W481 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 requirement for a pull-up

resistor. An Intelligent Power Module, Power MOSFET, or IGBT

can be driven directly.

Propagation delay difference between devices has been

minimized to maximize inverter efficiency through reduced

switching dead time.

Applications



IPM Interface Isolation



Isolated IGBT/MOSFET Gate Drive



AC and Brushless DC Motor Drives



Industrial Inverters



General Digital Isolation

Functional Diagram

Note: A 0.1 μF bypass capacitor must be connected between

pins 4 and 6.
