Product 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 USBhost ports and higher power wall adapters. The MP2624 detects the input source type according to the USBBattery 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 2.0A

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 together with the input power supply at the same time.
