DESCRIPTION

The MP2624 is a 4.5A, highly integrated,

switching-mode battery charger IC for single-

cell Li-ion or Li-polymer batteries. This device

supports NVDC architecture with power path

management suitable for different portable

applications, such as tablets, MID, and smart

phones.

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 MP2624 supports a wide range of input

sources, including standard USB host ports and

wall adapters. The MP2624 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.

Also, this device is compliant with USB2.0 and

USB3.0 power specifications by adopting a

proper input current and voltage regulation

scheme. In addition, the MP2624 supports USB

On-The-Go operation by supplying 5V with

current up to 1.3A.

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 (e.g. 3.6V).

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, the power path

management reduces automatically the charge

current 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 both the system and the

input power supply at the same time.

The MP2624 is available in a QFN-22

3mm x 4mm package.
