Package

The MP2617H is a monolithic, switch-mode,

battery charger with power path management

for single-cell Li-ion batteries in a wide range of

tablets and other portable devices. The

MP2617H integrates a synchronous buck

regulator that provides regulated voltage to

power the system output and charge the battery

simultaneously. The MP2617H supports both

USB and high-power DC adapter inputs. In

USB mode, the input current limit can be

programmed to 450mA or 825mA via the logic



pins

USB2.0

and

USB3.0

specifications. When the adapter input is

present, the input current can also be limited to

avoid overloading the DC adapter. The input

current limit can be programmed up to 3A.



Smart power path management allows the

MP2617H to regulate the system voltage for

powering an external load and charging the

battery independently and simultaneously. This

allows for immediate system operation, even

under missing or deeply discharged battery

conditions. When the input current limit is

reached, the system load is satisfied first, and

then the charger uses the remaining current to

charge the battery. Additionally, the smart

power path control allows for an internal

connection from the battery to the system 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.

APPLICATIONS



Smartphones

E-Books

GPS

Portable Media Players

Portable Handheld Solutions

Tablet PCs

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. “MPS” and “The Future of Analog IC Technology” are registered

The MP2617H features high integration with all

power switches integrated internally. No

external MOSFET, blocking diode, or current

sense resistor is required.

Two status monitor output pins are provided to

indicate the battery’s charge status and power

source status. Other features include trickle

charge, battery temperature monitoring, and

timer and thermal limiting regulation on the chip.

The MP2617H is available in a QFN-20

(3mmx4mm) package.
