Controller IC Chip - MAX8724ETI MAX8724E MAX8724 chip for laptop- Integrated portable calculator chip(SKU.1-CHIP0678)
The MAX1908/MAX8724 highly integrated, multichemistrybattery-charger control ICs simplify the construction ofaccurate and efficient chargers. These devices use ana-log inputs to control charge current and voltage, and canbe programmed by the host or hardwired. The MAX1908/MAX8724 achieve high efficiency using a buck topologywith synchronous rectification.The MAX1908/MAX8724 feature input current limiting.This feature reduces battery charge current when theinput current limit is reached to avoid overloading the ACadapter when supplying the load and the battery chargersimultaneously. The MAX1908/MAX8724 provide outputsto monitor current drawn from the AC adapter (DC inputsource), battery-charging current, and the presence ofan AC adapter. The MAX1908’s conditioning charge fea-ture provides 300mA to safely charge deeply dischargedlithium-ion (Li+) battery packs.The MAX1908 includes a conditioning charge featurewhile the MAX8724 does not.The MAX1908/MAX8724charge two to four series Li+cells, providing more than 5A, and are available in aspace-saving 28-pin thin QFN package (5mm ×5mm).An evaluation kit is available to speed designs.
