DESCRIPTION
The MP2629 is a 4.5A highly-integrated
switching-mode battery charger IC for single-
cell Li-ion or Li-polymer battery. This device
supports the NVDC architecture with power
path management suitable for different portable
applications such as tablet, MID and smart
phones. Its low impedance power path
optimizes efficiency, reduces battery charging
time and extends battery life. The I
2
C serial
interface with charging and system settings
allow the device to be flexibly controlled.
The MP2629 supports a wide range of input
sources, including standard USB host port and
higher power wall adapter with fast charge
capability. The MP2629 supports USB On-The-
Go operation by supplying 5V with 3.0A or Type
C source mode.
The power path management regulates the
system voltage slightly above the battery
voltage as long as the battery is above the
minimum programmable level and the input
power source is not limited. With this feature,
the system is able to keep operating even when
the battery is completely depleted or removed.
When the input source current or voltage limit is
reached, the power path management
automatically reduces the charge current to
meet the priority of the system power
requirement. If the system current keeps
increasing, even when the charge current is
reduced to zero, the supplement mode allows
the battery to power the system together with
the input power supply at the same time.
