... The adapter charge input constant current level can be programmed up to 1.5A for rapid charging applications. In the absence of a high current adapter input source, the AAT3686 can be powered from a USB port VBUS sup- ply. Depending on the USB port type, the AAT3686 con- stant charge current can be externally programmed for two levels, USB high and USB low, for maximum con- stant current charge levels up to 500mA ...

... When the input supply is disconnected or drops below UVLO the charger will automatically enter power-saving sleep mode. Consuming an ultra-low 0.3µA in sleep mode (1µA for AAT3686-1), the AAT3686 minimizes battery drain when it is not charging. This feature is particularly useful in applications where the input supply level may fall below the battery charge or under-voltage lockout level ...
