2A Switching Charger with NVDC
Power Path Management
For Single Cell Li+ Battery
The MP2625 is a monolithic switch mode
battery charger with power path management
for single-cell Li-ion batteries in a wide range of
tablet and other portable devices. It integrates a
synchronous BUCK regulator to provide
regulated voltage for powering the system
output and at the same time charging the
battery. This device supports both USB and
high power DC adapter input. In USB mode, the
input current limit can be programmed to
450mA or 825mA via the logic pins to cover the
USB2.0 and USB3.0 specifications. When the
adapter input is present, the input current can
also be limited in order to avoid overloading of
the DC adapter. Input current limit can be
programmed up to 2A.
The smart power path management allows
MP2625 to regulate the system voltage for
powering an external load and charging the
battery independently and simultaneously. This
allows immediate system operation even under
missing or deeply discharged battery. When the
input current limit is reached, the system load is
satisfied in priority, then the charger will take
the remaining current to charge the battery.
Additionally, the smart power path control
allows an internal connection from battery to the
system in order to supplement additional power
to the load in the event the system power
demand increases over the input limited power
or the input is removed.
The MP2625 features high integration with all
the power switches included inside. No external
MOSFET, blocking diodes, or current sense
resistor is required.
Two status monitor output pins are provided to
indicate the battery charge status and power
source status. Other features include trickle
charge, battery temperature monitoring, timer
and thermal limiting regulation on chip.
