ACPL-M484

ACPL-M484/P484/W484 Positive Logic High CMR Intelligent Power Module and Gate Drive Interface Optocoupler Data Sheet Description The ACPL-M484/P484/W484 fast speed optocoupler contains a AlGaAs LED and photo detector with built-in Schmitt trigger to provide logic-compatible waveforms, eliminating the need for additional wave shaping. The totem pole output eliminates the need for a pull up resistor and allows for direct drive Intelligent Power Module or gate drive. Minimized propagation delay difference between devices makes these optocouplers excellent solutions for improving inverter efficiency through reduced switching dead time.
