The MAX1908 evaluation kit (EV kit) is an accurate and efficient multichemistry battery charger. It uses analog inputs to control charge voltage and current. The EV kit can charge 2 to 4 series lithium-ion (Li+) cells with a current up to 3A. High efficiency is achieved by a buck topology with synchronous rectification. The EV kit provides outputs that can be used to monitor the input current, the battery-charging current, and the presence of an AC adapter.
