ACPL-P481
ACPL-P481 is High CMR Optocoupler manufactured by Avago Technologies.
Description
The high-speed ACPL-P481/W481 optocoupler contains a Ga As P 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
