DESCRIPTION

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

to

cover

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.

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.
