ACPL-P481 and ACPL-W481 Inverted Logic, High CMR Optocoupler for Intelligent Power Modules and IGBT/MOSFET Gate Drive Data Sheet 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 Functional Diagram Anode 1 6 VCC N.C.
