Package
The MP2617H is a monolithic, switch-mode,
battery charger with power path management
for single-cell Li-ion batteries in a wide range of
tablets and other portable devices. The
MP2617H integrates a synchronous buck
regulator that provides regulated voltage to
power the system output and charge the battery
simultaneously. The MP2617H supports both
USB and high-power DC adapter inputs. In
USB mode, the input current limit can be
programmed to 450mA or 825mA via the logic
pins
to
cover
USB2.0
and
USB3.0
specifications. When the adapter input is
present, the input current can also be limited to
avoid overloading the DC adapter. The input
current limit can be programmed up to 3A.
Smart power path management allows the
MP2617H to regulate the system voltage for
powering an external load and charging the
battery independently and simultaneously. This
allows for immediate system operation, even
under missing or deeply discharged battery
conditions. When the input current limit is
reached, the system load is satisfied first, and
then the charger uses the remaining current to
charge the battery. Additionally, the smart
power path control allows for an internal
connection from the battery to the system 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.
APPLICATIONS

The MP2617H features high integration with all
power switches integrated internally. No
external MOSFET, blocking diode, or current
sense resistor is required.
Two status monitor output pins are provided to
indicate the battery’s charge status and power
source status. Other features include trickle
charge, battery temperature monitoring, and
timer and thermal limiting regulation on the chip.
The MP2617H is available in a QFN-20
(3mmx4mm) package.
