Description

The high-speed ACPL-P481/W481 optocoupler contains

a GaAsP LED, photo detector and a Schmitt trigger that

eliminates the need for external waveform conditioning

circuits.

The totem pole output eliminates the need 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
