ADUM5401 Startup

Hi , 

We are looking at ADUM5401 for a replacement for ISOW7841.

I have one quick question, The TI part requirest the device to be powered within 10 ms of UVLO.

But the circuit that we are looking at takes 200 ms from UVLO to 90 %.

Do you have details with regards to the slew rate?

Thanking you 

With best regards and wishes

  • 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.
