MP2650

I²C-Controlled 5A Buck or Boost Charger

with NVDC Power Management and USB OTG

for 2-Cell to 4-Cell Battery Pack Applications

DESCRIPTION

FEATURES

The MP2650 is a highly integrated buck or

boost charger IC with narrow-voltage DC

(NVDC) power path management and USB On-

The-Go (OTG) for battery packs with 2 cells to

4 cells in series. All power MOSFETs are

integrated to provide a compact system solution

size.

Range

•

Up to 28V (20ns) Sustainable V_IN

Configurable V_INLimit

The IC can accept a wide input voltage (V_IN)

range for charging, with a 21V maximum. The

device has two operating modes during the

charging process: boost charging mode and

buck charging mode, depending on V_INand the

cell count.

I²C Interface to Support Flexible Parameter

Control

•

With the I²C interface, the MP2650 can be

flexibly configured to set the parameters in both

charging mode and OTG mode. Parameters

include the input current (I_IN) limit, V_INlimit,

charging current, battery charge voltage

regulation, and safety charge timer. It can also

provide the operation statuses through status

and fault registers.

•

To guarantee safe operation, the IC limits the

die temperature to a preset value of 120°C.

Other safety features include input over-voltage

protection (OVP), battery OVP, system OVP,

NVDC power path management regulates the

system voltage within a narrow DC range to

provide an optimized system bus voltage for the

rails at the system bus. With this feature, the

system can continue operating even when the

battery is completely depleted or removed.
