Controller IC Chip - Mofset MAX8765ETI MAX8765 8765E chip for laptop- Integrated portable calculator chip(SKU.1-CHIP0633)
The MAX1908/MAX8724/MAX8765 highly integrated, multi-chemistry battery-charger control ICs simplify the construc-tion of accurate and efficient chargers. These devices useanalog inputs to control charge current and voltage, andcan be programmed by the host or hardwired. TheMAX1908/MAX8724/MAX8765 achieve high efficiencyusing a buck topology with synchronous rectification.The MAX1908/MAX8724/MAX8765 feature input currentlimiting. This feature reduces battery charge current whenthe input current limit is reached to avoid overloading theAC adapter when supplying the load and the batterycharger simultaneously. The MAX1908/MAX8724/MAX8765 provide outputs to monitor current drawn fromthe AC adapter (DC input source), battery-charging cur-rent, and the presence of an AC adapter. The MAX1908’sconditioning charge feature provides 300mA to safelycharge deeply discharged lithium-ion (Li+) battery packs.The MAX1908 includes a conditioning charge featurewhile the MAX8724/MAX8765 do not.The MAX1908/MAX8724/MAX8765 charge two to fourseries Li+ cells, providing more than 5A, and are avail-able in a space-saving, 28-pin, thin QFN package (5mm×5mm). An evaluation kit is available to speed designs.
