AAT3673中文资料1.6A Dynamic Battery Charger and Power Management IC数据手册Skyworks规格书

描述 Description

The AAT3673 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. For increased safety, the AAT3673 includes over-voltage input protection (OVP) up to 28V.
The AAT3673 provides charging current and system power management from a single input that may be supplied by an AC adapter or USB port power source (ADP). 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 AAT3673 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 AAT3673 has a digitally controlled thermal loop which allows the maximum possible charging current for any given ambient temperature condition.
Battery temperature, voltage and charge state are monitored for fault conditions. The AAT3673-1/-2/-4/-5 has two status monitor output pins (STAT1 and STAT2), and the AAT3673-3/-6 has one status monitor output (STAT1) provided to indicate battery charge status by directly driving external LEDs.
The AAT3673 is available in a Pb-free, thermally enhanced, space-saving 16-pin 4x4mm TDFN package.
