The MAX1908/MAX8724/MAX8765 highly integrated, multichemistry battery-charger control ICs simplify the construction of accurate and efficient chargers. These devices use analog inputs to control charge current and voltage, and can be programmed by the host or hardwired. The MAX1908/MAX8724/MAX8765 achieve high efficiency using a buck topology with synchronous rectification. The MAX1908/MAX8724/MAX8765 feature input current limiting. This feature reduces battery charge current when the input current limit is reached to avoid overloading the AC adapter when supplying the load and the battery charger simultaneously. The MAX1908/MAX8724/ MAX8765 provide outputs to monitor current drawn from the AC adapter (DC input source), battery-charging current, and the presence of an AC adapter. The MAX1908's conditioning charge feature provides 300mA to safely charge deeply discharged lithium-ion (Li+) battery packs. The MAX1908 includes a conditioning charge feature while the MAX8724/MAX8765 do not. The MAX1908/MAX8724/MAX8765 charge two to four series Li+ cells, providing more than 5A, and are available in a space-saving, 28-pin, thin QFN package (5mm x 5mm). An evaluation kit is available to speed designs.
