[quote user="Michael Allwright"]The datasheet for the bq24160 states that if a CDP/DCP host is connected the limit will be increased to draw up to 1.5A, doesn't this then violate the standards set in B1.2 if high speed mode is selected (or worse, if it being negotiated at the time)?[/quote]
I think that BQ24160 will go into 100mA mode if host CDP does not supply 1.5 [A].
