When the input supply is disconnected or drops
below UVLO or EN = 0, the charger will automati-
cally 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. In such cases where the AAT3686
input voltage drops, the device will enter sleep
mode and automatically resume charging once the
input supply has recovered from its fault condition.
