Description
The MAX1908/MAX8724/MAX8765/MAX8765A highly integrated, multi-chemistry 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/MAX8765A achieve high efficiency using a buck topology with synchronous rectification.
n
nThe MAX1908/MAX8724/MAX8765/MAX8765A feature input current limiting. This feature reduces the 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/MAX8765A 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.
