Broadcom ACNU-4803/-4804 gate drive interface optocouplers
The ACNU-4803 and ACNU-4804 High CMR Intelligent Power Module are high-speed optocouplers containing a AlGaAs LED and photo detector
The ACNU-4803 and ACNU-4804 High CMR Intelligent Power Module are high-speed optocouplers containing a AlGaAs LED and photo detector with a built-in Schmitt trigger to provide logic-compatible waveforms, eliminating the need for additional wave shaping.
- 11-mm creepage and 10.5-mm clearance
- Positive output type (totem pole output)
- Truth table guaranteed: Vcc from 4.5V to 30V
- Performance specified for common IPM applications over industrial temperature range
The totem pole output eliminates the need for a pull-up resistor and allows for direct drive of Intelligent Power Module or as a gate driver. Minimized propagation delay difference between devices makes these High CMR Intelligent Power Module optocouplers an excellent solution for improving inverter efficiency through reduced switching dead time. The ACNU-4803 has an increased common mode transient immunity of 30kV/µs minimum at VCM = 1000V guaranteed over wide operating temperature range, whereas the ACNU-4804 has an increased common mode transient immunity of 50kV/µs minimum at VCM = 1500V guaranteed over wide operating temperature range.
