The MAX1908/MAX8724/MAX8765/MAX8765A highlyintegrated, multichemistry battery-charger control ICssimplify the construction of accurate and efficient charg-ers. These devices use analog inputs to control chargecurrent and voltage, and can be programmed by the hostor hardwired. The MAX1908/MAX8724/MAX8765/MAX8765A achieve high efficiency using a buck topologywith synchronous rectification.The MAX1908/MAX8724/MAX8765/MAX8765A featureinput current limiting. This feature reduces batterycharge current when the input current limit is reachedto avoid overloading the AC adapter when supplyingthe load and the battery charger simultaneously. TheMAX1908/MAX8724/MAX8765/MAX8765A provide out-puts to monitor current drawn from the AC adapter (DCinput source), battery-charging current, and the pres-ence of an AC adapter. The MAX1908’s conditioningcharge feature provides 300mA to safely charge deeplydischarged lithium-ion (Li+) battery packs.The MAX1908 includes a conditioning charge featurewhile the MAX8724/MAX8765/MAX8765A do not.The MAX1908/MAX8724/MAX8765/MAX8765A charge twoto four series Li+ cells, providing more than 5A, and areavailable in a space-saving, 28-pin, thin QFN package (5mm× 5mm). An evaluation kit is available to speed designs.
