ISOW7842: ISOW7842 VCC=3.3V VISO=5V Load Capability

Jack CCY

Part Number: ISOW7842

Hi expert,

If I configure the ISOW7842 VCC=3.3V, VISO=5V, will it work? And how about the efficiency at this time?

How about the load current of VISO at this time? How about its load capability to drive load?

Thank you.

Best Regards

Hi Jack,

Thanks for posting your question on the digital isolators forum.

Vcc=3.3V and VISO=5V is not supported by the ISOW78xx device currently.

The following modes are currently supported:

Since this configuration is not supported I do not have any data to share with you for efficiency, load current, or ability to drive load.

Best regards,

Dan
