MP2672

Boost Charger with Cell Balance for

2-Cell Series Lithium-Ion Battery

DESCRIPTION

FEATURES

The MP2672 is a highly integrated, flexible

switch-mode battery charger IC for a Lithium-ion

battery with two cells in series, which is used in

a wide range of portable applications.



4.0V to 5.75V Input Operation Voltage

Up to 14V Sustainable Voltage

Up to 2A Programmable Charge Current for

Battery with 2 Cells in Series

Compatible with Host Control and

Standalone Mode

NVDC Power Path Management

Programmable Input Voltage Limit

Programmable Charge Voltage with 0.5%

Accuracy

No External Sense Resistor Required

Integrated Cell Balancing Circuit for Cell

Mismatch

Preconditioning for Fully Depleted Battery

Flexible New Charging Cycle Initiation

Charging Operation Indicator in Standalone

Mode



When the input power supply is present, the

MP2672 operates in boost mode to charge the

battery with two cells in series. When charging is

enabled, the MP2672 automatically detects the

battery voltage and charges the battery in three

phases: pre-charge, constant-current charge,

and constant-voltage charge. Other features

include charge termination and auto-recharge.



The MP2672 also has a narrow voltage DC

(NVDC) power structure. When the battery is

weak, the MP2672 regulates the system output

at the minimum voltage level to power the

system instantly and charge the battery via the

battery FET simultaneously.



Missing Battery Detection

I²C Port for Flexible System Parameter

Setting and Status Reporting in Host

Control Mode

The MP2672 also has cell balance function. It

monitors the voltage across each cell and

equalizes cell voltages once the difference

exceeds the mismatch threshold.



Negative Temperature Coefficient Pin for

Temperature Monitoring Compliant with

JEITA Standards

Built-In Charging Protection and

Programmable Safety Timer

MOSFET Cycle-by-Cycle Over-Current

Protection

Thermal Regulation and Thermal Shutdown

Available in a QFN-18 (2mmx3mm)

Package

The MP2672 has two configuration modes:

standalone mode and host control mode. In

standalone mode, the charging parameters can

be configured by the hardware pins. In host

control mode, the charging parameter can be

configured by the I²C registers.



The MP2672 has diversified and robust

protections. It has a thermal regulation loop to

decrease the charge current if the junction

temperature exceeds the thermal loop threshold.

It also has battery temperature protection

compliant with JEITA standards. Other safety

features include input over-voltage protection,

over-voltage

protection,

thermal

shutdown, battery temperature monitoring, a

watchdog timer, and a programmable back-up

timer to prevent prolonged charging of a dead

battery.
