MP2676 Datasheet, PDF (1/10 Pages) Monolithic Power Systems – Li-Ion Charger Protection IC With Integrated P-MOSFET

The Future of Analog IC Technology
DESCRIPTION
The MP2676 is a highly integrated circuit
designed to provide complete Li-ion battery
charger protection against input over voltage,
input over current and battery over voltage. The
IC continuously monitors the input voltage, the
input current and the battery voltage, when any
of the monitored parameters exceeds its
threshold, the IC immediately turns off the
internal N-channel MOSFET to remove the
power from the charge system before any
damage occurs. Moreover, all protections also
have blanking times against false triggering due
to voltage spikes or current transients. The IC
also features thermal shutdown protection, if
the temperature exceeds 140ºC, MP2676 will
turn off the internal MOSFET bridging ACIN and
CHRIN.
MP2676 integrates a P-channel MOSFET with
the body diode reverse protection to replace the
external P-channel MOSFET and blocking
diode for charge function of portable devices
with PMIC (Power Management IC). The above
features and small package make the MP2676
an ideal part for portable applications.
