MP2615C 1 or 2 Cell Li-Ion Battery Chargers Monolithic Power Systems (MPS) MP2615C 1 or 2 Cell Li-Ion Battery Chargers can deliver 2.1A of charge current for single-cell or dual-cell Li-ion or Li-polymer applications. The 2.1A of charge current can be configured via an accurate current-sense resistor across the entire input range. The MP2615C regulates the charge current and full battery voltage using two control loops to achieve a high-accuracy constant current (CC) charge and constant voltage (CV) charge.
