Hi ,

I would like to ask a question on the ADuM5201 self-regulation mode configuration.

I' m referring  to Table 22 on page 13 in the ADuM520X  datasheet Rev.B, but I cannot be

100% sure about where and how to connect RCin pin and RCsel pin to  , respectively.

So , I would liek to ask the following questions.

Qustion:

In ADuM5201 self-regulation mode,

1 )  Should  the RCin pin be directly tied to GND, or with a pull-down resistor?

    If the latter is true , what the resistor value  should be?

2) Should the RCsel pin be pulled -up to VDD1 with a resistor?

 

Your earliest advice would be appreciated.

Best Regards,

Lux
