ADUM5401 Startup

Hi,

Could you also let me know VISO START-UP ISSUES details in Auto grade?

Do this working has no effect on the non-auto device also. 

Thanking you 

With regards 

Kabekami-san: The ADuM5401W datasheet describes the recommended version for startup, as shown below:

The ADuM5401W-1/ADuM5402W-1/ADuM5403W-1 versions of the isolators provide an upgraded voltage reference to ensure proper startup under all load conditions (see the Ordering Guide for more information).

There is no issue known for startup with these versions.

Regards, Brian

Hi Brian, 

Thanking you for the information.

I am planning to use the non Auto part for my project.

And my slew rate for power-up sequence it in 100ms order. Does the non-auto part does not have a voltage reference?

Thanking you 

With best regards and wishes 

Kabekami:

The non-auto part has a reference but it was revised and has no known start issues.

Regards, Brian
