DATA SHEET AAT3672 1.6A Dynamic Battery Charger and Power Manager General Description The AAT3672 BatteryManager 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.
