    CYUSB2014 Power Question

    user_51803100

      Hello

         

       

         

      Couple Questions.

         

      1) Clarification question on the Vramp spec.  The Voltage Ramp on my supplies which are 3.3V and 1.2V need to be monotonic.  That means the just need to have a smooth and consistent rise rate.  They do not have to have the same ramp rate?  Basically my 3.3V and 1.2V will reach these levels at the same time and therefore their rise rate will be different.

         

      2) What is the current draw on the VBUS and VBATT pins?  The Vbus pin states it has an internal regulator to power the USB I/O pins?  Since I'm only using the USB 2.0 function I don't know what the current draw is on these 2 pins? 

         

       

         

      Thanks
