3A Switching Charger with NVDC

Power Path Management

For Single Cell Li+ Battery

DESCRIPTION

FEATURES

The MP2617A / MP2617B is a monolithic

switch mode battery charger with power path

management for single-cell Li-ion batteries in a

wide range of tablet and other portable devices.

It integrates a synchronous BUCK regulator to

provide regulated voltage for powering the

system output and at the same time charging

the battery. This device supports both USB and

high power DC adapter input. In USB mode, the

input current limit can be programmed to

450mA or 825mA via the logic pins to cover the

USB2.0 and USB3.0 specifications. When the

adapter input is present, the input current can

also be limited in order to avoid overloading of

the DC adapter. Input current limit can be

programmed up to 3A.



4V to 10V Operating Input Voltage

Smart Power Path Management

Five Control Loops: Input Current Limit,

Input



No External Blocking Diode and Sense

Resistor Required

Charging Operation Indicator

Built-in Programmable Charging Timer

Thermal Limiting Regulation on Chip

Battery Temperature Monitor



The smart power path management allows

MP2617A and MP2617B to regulate the system

voltage for powering an external load and

charging the battery independently and

simultaneously. This allows immediate system

operation even under missing or deeply

discharged battery. When the input current limit

is reached, the system load is satisfied in

priority, then the charger will take the remaining

current to charge the battery. Additionally, the

smart power path control allows an internal

connection from battery to the system in order

to supplement additional power to the load in

the event the system power demand increases

over the input limited power or the input is

removed.

The MP2617A / MP2617B features high

integration with all the power switches integrate

inside. No external MOSFET, blocking diodes,

or current sense resistor is required.

Two status monitor output pins are provided to

indicate the battery charge status and power

source status. Other features include trickle

charge, battery temperature monitoring, timer

and thermal limiting regulation on chip.

The MP2617A / MP2617B is available in QFN

3mmx4mm package.
