MP2617A, MP2617B
3A Switching Charger with NVDC
Power Path Management
For Single Cell Li+ Battery
DESCRIPTION
The MP2617A / MP2617B 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 3A.
The smart power path management allows
MP2617A and MP2617B 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 MP2617A / MP2617B 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.
The MP2617A / MP2617B is available in QFN
3mmx4mm package.
