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 dierence between devices has been
minimized to maximize inverter eciency 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
