MP26121

28V, 1A Li + Linear Battery Charger

with 10% Battery-Full Threshold

and Flexible NTC Interface

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MP26121 is a linear, high-performance

single cell Li-Ion/Li-Polymer battery charger. By

integrating high voltage input protection into the

charger IC, the MP26121 can tolerate an input

surge up to +28V.

•

Interfaces to Many NTC Resistor Values

Proprietary V_INSurge Protection up to 28V

Programmable Charge Current up to 1A

1% Voltage Accuracy

10% Battery-Full Threshold

No Reverse Blocking Diode Required

Intelligent Thermal Management

Trickle Charge

7V Input OVP

Auto Recharge

Charge-Timer

Fault and Charge Status Indicators

The device features constant current (CC) and

constant voltage (CV) charging modes with

programmable charge currents (200mA to 1A),

current blocking, and trickle charge. The device

also provides fault and charge status

indications to the system.

For guaranteed safe operation, the MP26121

reduces charge current when the device

reaches high temperature (due to limited PCB

space). Other safety features include battery

temperature monitoring and programmable

timer to complete the charging cycle.

APPLICATIONS

•

Cell Phones

Digital Cameras

Smart Phones

PDAs

The MP26121 is available in 10-pin 3mm x

3mm QFN packages.
