About ADuM6201 Output Voltage

Hi,

My customers are considering using ADuM 6201.
So I got a question.


It seems that we want to connect ADuM 142 and another ADuM 6201 behind Viso of ADuM 6201.

Since the regulator is contained in ADuM6201, I think that there is no problem.
Just to be sure, I'd like to confirm, but is there any problem connecting the two ICs to the power supply on the secondary side?

Best Regards,

Yuya

    The ADuM6201 can only supply 5V to 3.3V at 100mA max. It may not work well as a balanced system with 2 ADuM6201s VISO tied together to try to provide 200mA.

    For VISO of 400mA, the ADuM6201 using 4 would not be able to provide the 400mA output needed.

    The ADuM447x can provide 5V to 3.3V at 400mA with 4 digital isolator channels. If you need to you can add the ADuM14x for more channels.

    How many total channels to you need and what is the application for the 400mA?
