AAT3672
Description
The AAT3672 Battery Manager is a highly integrated single-cell (4.2V) lithium-ion/polymer battery charger and system power management IC that enables simultaneous battery charging and system load management.
The AAT3672 provides charging current and system power management from a single input that may be supplied by an AC adapter or USB port power source. This device allows the user to program the battery charge current up to 1.6A depending on the current shared with the system output. A battery charge timeout timer is provided for charging safety and the charge termination current is also user-programmable.
The AAT3672 employs a battery charge current reduction function that enables continued system operation in the event the input source can not supply the required load current. When operated under excessive thermal conditions, the AAT3672 has a digitally controlled thermal loop which allows the maximum possible charging current for any given ambient temperature...
