ACT2802 integrates all the functions, a spare battery pack needs, including switching charger, boost converter and LED indicator. ACT2802 runs in 1.1 mhz switching charger 0.55 mhz, improving converter allows small external inductors and capacitors. ACT2802 provides direct power path from the input to the output of the programmable current limit, while providing the power switch charger. Higher priority than the output of the battery charger, if programmed input current limit is reached. Pretreatment ACT2802 battery charges the whole cycle, rapid and constant voltage constant current charging until the end. The battery charger is adjusted to 110 ° C heat current monitoring. ACT2802 improve the battery voltage converter to step 5 v. Improve the function of high efficiency converter, constant current regulation, short circuit protection and over-voltage protection. ACT2802 3.5 ma provide constant current to drive the 4 led indicate battery charge status and charge.
