DESCRIPTION
The MP2624A is a 4.5A, highly integrated,
switching-mode, battery charger IC for single-
cell Li-ion or Li-polymer batteries. The MP2624A
supports NVDC architecture with power path
management and is suitable for various portable
applications. Its low impedance power path
optimizes efficiency, reduces battery charging
time, and extends battery life. The I2C serial
interface with charging and system settings
allows the device to be controlled flexibly.
The MP2624A supports a wide range of input
sources, including standard USB host ports and
wall adapters. The MP2624A detects the input
source type according to the USB Battery
Charging Spec 1.2 (BC1.2) and then informs the
host to set the proper input current limit. In
addition, the MP2624A supports USB On-The-
Go operation by supplying 5.0V with current up
to1.3A.
The power-path management regulates the
system voltage slightly above the set maximum
voltage between the battery voltage and the I2C
programmable lowest voltage level. With this
feature, the system is able to operate even when
the battery is depleted completely or removed.
When the input source current or voltage limit is
reached, power path management reduces the
charge current automatically to meet the priority
of the system power requirement. If the system
current continues 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
simultaneously.
The MP2624A is available in a QFN-22
(3mmx4mm) package.
