MP2673

4.5A, Fast Battery Charger with 3A Boost

System Current and Programmable

Battery Discharge Current Limit

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MP2673 is a highly integrated, flexible,

switch-mode, battery charge management and

system power-path management device

designed for single-cell Li-ion and Li-polymer

batteries used in a wide range of portable

applications.



4.0V to 14V Operation Voltage Range

Up to 24V Sustainable Input Voltage

BC1.2 Detection with I²C Programmable

DP1/DM1 Control

Integrated Input-Current-Based and Input-

Voltage-Based Power Management

Function

Up to 4.5A Programmable Charge Current

Reverse Boost Operation Mode with up to

3A Output Current and Adjustable 5V to

12V Output Voltage

Analog Voltage Output IB Pin for Battery

Current Monitor

Programmable 3.1 - 4.675V Charge Voltage

with 0.5% Accuracy

Four-LED Battery Gauge Indicators

JEITA-Compatible Negative Temperature

Coefficient (NTC) Protection

Programmable Timer Back-Up Protection

Thermal Regulation and Thermal Shutdown

USB Output Cable Impedance

Compensation

Integrated Short-Circuit Protection (SCP) for

Boost Mode



The IC has two operating modes (charge mode

and boost mode) to allow for management of the

system and battery power based on the state of

the input and output.



When input power is present (up to 14V), the

device operates in charge mode. The device

detects the battery voltage automatically and

charges the battery in four phases: trickle current

charge, pre-charge, constant-current charge,

and constant-voltage charge.



In the absence of an input source, the MP2673

switches to boost mode to power SYS from the

battery. The IC can provide a wide boost voltage

to SYS by adjusting the feedback voltage at FB.



With the I²C interface, the IC can flexibly

program charging and boosting parameters such

as input current limit, charging current, battery

regulation (charge full) voltage, safety timer,

boost output current limit, etc. The MP2673 can

also provide the operation status through the I²C

registers and remaining battery capacity via four

LEDs.



Integrated Short-Circuit Protection (SCP)

and Over-Voltage Protection (OVP) for

Pass-Through Path

Integrated 8-Bit SAR ADC for Battery-

Voltage Measurement



To guarantee safe operation, the IC limits the die

temperature to a preset value of 120°C (default).

Other safety features include input over-voltage

protection (OVP), battery over-voltage protection

(OVP), thermal shutdown, and battery

temperature monitoring.

APPLICATIONS



Sub-Battery Applications

Power-Bank Applications for Smart phones,

Tablets, and Other Portable Devices
