The Future of Analog IC Technology MP2619 2A, 24V Input, 600kHz 2-3 Cell Switching Li-Ion Battery Charger With System Power Path Management DESCRIPTION The MP2619 is a monolithic switching charger for 2-3 cell Li-Ion battery packs with a built in internal power MOSFET. It achieves up to 2A charge current with current mode control for fast loop response and easy compensation. The charge current can be programmed by sensing the current through an accurate sense resistor. MP2619 regulates the battery voltage and charge current using two control loops to realize high accuracy CC charge and CV charge. The system power path management function ensures continuous supply to the system by automatically selecting the input or the battery to power the system.
