MP2676 - Li-Ion Charger Protection

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.

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.

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.
