The Future of Analog IC Technology
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 2mmx2mm
QFN package.
