MP2669

5A, Battery Charger

with 3A Boost System Current and

Fast-Charge Capability

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MP2669 is a highly integrated, switch-

mode, battery charge and system power-path

management device designed for a single-cell

Li-ion or Li-polymer battery for use 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

Functions

Power

Management

The IC has different operating modes (charge

mode, boost mode, and sleep mode) to allow

for management of the system and battery

power based on the state of the input and

output.



Up to 4.5A Programmable Charge Current

Reverse Boost Operation Mode with up to

3A Output Current and Adjustable 5V to

14V Output Voltage to Support QC3.0 with

When an 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,

and constant voltage charge.

Current Monitor

Programmable 3.1 - 4.675V Charge Voltage

with 0.5% Accuracy



The IC has an integrated IN-to-SYS pass-

through path to pass the input voltage to the

system, even when charging is disabled. The

path-through path has high priority over the

charging path. The MP2669 manages the input

power and meets the priority of the system

power demand with the integrated input current

and input voltage regulation function.



Four LED Battery Gauge Indicators

JEITA-Compatible Negative Temperature

Coefficient Protection in both Charge and

Discharge Mode



Thermal Regulation and Thermal Shutdown

Integrated Short-Circuit Protection (SCP)

and Over-Voltage Protection (OVP) for

Pass-through Path

Integrated 8-Bit SAR ADC for Battery

Voltage Measurement



In the absence of the input source, the MP2669

enters sleep mode to minimize the power

dissipation of the battery. If the system load is

at SYS, the MP2669 switches to boost mode to

power SYS from the battery. When working with

the interface IC, the MP2669 can support

QC3.0 with output short protection.



Available in

Package

QFN-28 (4mmx4mm)

With the I²C interface, the IC can flexibly

program the charging and boosting parameters,

providing the operation status.

APPLICATIONS



Sub-Battery Applications

Power-Bank Applications for Smartphones,

Tablets, and Other Portable Devices

To guarantee safe operation, the IC limits the

die temperature to a preset value 120°C

(default). The IC also provides other safety

features, including input over-voltage protection

(OVP), battery OVP, thermal shutdown, and

battery temperature monitoring.

All MPS parts are lead-free, halogen-free, and adhere to the RoHS directive. For

MPS green status, please visit the MPS website under Quality Assurance.
