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.
