It is a stand-alone charging solution, with just one external compo- nent required for complete functionality. The AAT3683 precisely regulates battery charge voltage and current for 4.2V lithium-ion/polymer battery cells with constant current level being pro- grammed up to 1A for rapid charging applications. The charge termination current can be pro- grammed by an external resistor. The AAT3683 is rated for operation from -40°C to +85°C. In the event of operating ambient tempera- tures exceeding the power dissipation abilities of the device package for a given constant current charge level, the charge control will enter into thermal limit. AAT3683-2 and -3 provide one status monitor out- put pin (STAT) by directly driving one external LED to indicate the battery charging state. AAT3683-4 provides two status pins to indicate the battery charging state. Device junction temperature and charge state are fully monitored for fault conditions. In the event of an over-voltage or over-temperature failure, the device will automatically shut down, protecting the charging device, control system, and the battery under charge. During battery charging, the device temperature will rise. In some cases with adapter (ADP) charging, the power dissipation in the device may causethe junction temperature to rise to close to its thermal shutdown threshold. In the event of an internal over-temperature condition caused by excessive ambient operating temperature or excessive power dissipation condition, the AAT3683 enables a digi- |
