Product Description

The MP2674 is a high performance single cell Li-Ion/Li-Polymer battery charger protection circuit. By integrating high voltage input protection into the IC, the MP2674 can tolerate an input surge up to +30V. The device features input over voltage protection (OVP), battery over voltage protection (BOVP) and over charge current protection (OCP). The device also provides fault indications to the system when any of the protection events happens. For guaranteed safe operation, the MP2674 monitors its own internal temperature and turns off the MOSFET bridging VIN and OUT when the die temperature exceeds 150oC. The MP2674 is available in an 8-pin 2x2mm QFN package.
