The MAX1870A 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 any battery with charge current up to 2.4A. High efficiency is achieved by a buck-boost topology. The EV kit provides outputs that can be used to monitor the input current and the presence of an AC adapter.
The MAX1870A EV kit is a fully assembled and tested surface-mount printed circuit (PC) board.
