    CCG2 Power Savings

    jheaton_3303476

      I want to use USB-C PD3 as the primary power supply for my product(upstream facing port that Sinks power). When using a Powerbank as the source of power, via a USB-C cable, sometimes they will shut down the USB outlet power when current draw falls below a certain level. When this happens, you must unplug and re-insert the connector to wake up the port, not ideal for my application.

       

      I just hooked up my CY4521 evaluation kit to the powerbank and it performs as I would like, keeping the USB-C running (always on) without delivering much current to the port. I am starting my PCB layout now and want to make sure that my implementation will also perform this way (always on) and want to know if there is a software/firmware setting to disable/enable this behavior?
