製品説明

The EV2619-V-01A is an evaluation board for the MP2619, a switching, high performance 2-3 cell Li-Ion battery charger with built in internal power MOSFET for power path application.

MP2619 achieves up to 2A charge current over a wide input supply range. 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.

Fault condition protection includes time out control, battery full terminated control, thermal protection, battery temperature monitoring and protection. The board also indicates AC adapter power good and charge status indications to the system.

600kHz Switching Li-Ion Charger with System Power Path Management

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. Power path management separates charging current from system load. When the MP2619 realizes current sharing of the input current, charge current will drop down according to the increase of the system current.
Fault condition protection includes cycle ­by ­cycle current limiting, and thermal shutdown. Other safety features include battery temperature monitoring, charge status indication and programmable timer to finish the charging cycle.
The MP2619 is available in a 28-pin, 4mm x 5mm QFN package.
