TLV3691: Need comparator with over voltage on input pins.

Part Number: TLV3691

Hello,

I have a question about TLV3691 or really any voltage comparator that offers some type of over-voltage protection on the inputs. I have drawn a rough sketch of what I am trying to achieve. VCC supply needs to be capable of 1.2V - 5.5V. 

Case 1:

Case 2:

Do we have a voltage comparator that could achieve the above both cases 1 and 2?

Regards,

Tyler

    Hi Tyler,

    Unfortunately we do not have any devices that can operate down to 1.2V AND have the over the rail input capability. Can you divide down the input signals to be within the rails? the TLV3691 is the only device capable of operating down to 1.2V.
