About This Product

■Summary

The MP2619 is a monolithic switching charger for 2-3 cell Li-ion battery packs with internal power MOSFETs. Achieves up to 2A charging current with fast loop response and current mode control for easy compensation. The charging current is programmable by sensing the current through an accurate sense resistor. The MP2619 uses two control loops to regulate battery voltage and charging current, providing highly accurate CC and CV charging. System power path management features ensure continuous power to the system by automatically selecting power to the input or battery powering the system. Power path management separates charging current and system load. When the MP2619 achieves current sharing of the input current, the charging current decreases as the system current increases. Fault condition protection includes cycle-by-cycle current limiting and thermal shutdown. Other safety features include a battery temperature monitor, charging status display, and a programmable timer to end the charging cycle. The MP2619 is available in a 28-pin 4mm x 5mm QFN package.

■Features and benefits
