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. 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.
