  1. DA9053 USB charging - by alternative 5V source

    ... least 1A. This 5V source does not have the D+, D- connections and therefore the DA9053 cannot automatically determine the source's capability. Will the DA9053 allow charging from VBUS at arbitrary charging rate if the D+, D- inputs are unconnected ? Or, perhaps, is there a way of tieing these ...

  2. DA9053 USB charging questions

    I use a DA9053 inside a mobile device containing a li-ion battery. I'd like to be able to charge the main battery from the VBUS input and the datasheet claims this is possible "...while maintaining USB power specification compliance", however I cannot find any description or app note ...
