MP2678

Li-Ion Battery Charger

Protection Circuit With LDO Mode

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MP2678 is a high performance single cell

Li-Ion/Li-Polymer battery charger protection IC.

By integrating the high voltage input protection,

the MP2678 can tolerate an input surge up to

+30V.

•

Input Surge up to 30V

Input Over Voltage Protection

Proprietary Battery Over-Voltage Protection

Output Short-Circuit Protection

Soft-Stop to Prevent Voltage Spikes

Support up to 1.7A Load Current

Thermal Monitoring and Protection

Enable Function

The device operates like a linear regulator,

maintaining a 5V output with the input voltage

up to the over voltage protection threshold.

Fault Indication

2 mm×2mm QFN Package

MP2678 features input over voltage protection

(OVP), battery over voltage protection (BOVP)

and over charge current protection (OCP).

When any fault condition happens, the IC will

immediately turn off the internal N-MOSFET to

disconnect the charging circuit from the input.

The device also provides fault indications to the

system when any of the protection events

happens.

APPLICATIONS

•

Cell Phones

Smart Phones

PDAs

MP3 Players

Low-Power Handheld Devices

For guaranteed safe operation, the MP2678

monitors its own internal temperature and turns

off the internal N-MOSFET bridging IN and

OUT when the die temperature exceeds 140^oC.
