MP2624AGL-Z

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 high-power 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 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. 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.
