MP2624 2 I C Controlled 4.5A Single Cell USB / Adaptor Charger with Narrow VDC Power Path Management USB OTG and Shipping Mode The Future of Analog IC Technology DESCRIPTION FEATURES The MP2624 is a 4.5A, highly integrated, High Efficiency 4.5A 1.5MHz Buck Charger switching-mode battery charger IC for single- and 1.5MHz 1.3A Boost Mode to Support cell Li-ion or Li-polymer batteries. This device OTG supports NVDC architecture with power path o 94% Efficiency 2A management suitable for different portable o Fast Charge Time by Battery Path applications, such as tablets, MID, and smart Impedance Compensation phones. Its low impedance power path o USB OTG optimizes efficiency, reduces battery charging o 94% Efficiency 5V, 1.2A OTG 2 time, and extends battery life. The I C serial o Selectable OTG Current Outputs interface with charging and system settings 3.9V to 7.0V Operating Input Voltage Range allows the device to be controlled flexibly. Highest Battery Discharge Efficiency with 10m Battery Discharge MOSFET up to 9A The MP2624 supports a wide range of input Single Input USB Compliant Charge sources, including standard USB host ports and Narrow System Bus Voltage Power Path wall adapters. The MP2624 detects the input Management source type according to the USB Battery o Instant On Works with No Battery or Charging Spec 1.2 (BC1.2) and then informs Deeply Discharged Battery the host to set the proper input current limit. o Ideal Diode Operation in Battery Also, this device is compliant with USB2.0 and Supplemental Mode USB3.0 power specifications by adopting a Constant-Off-Time Control to Reduce proper input current and voltage regulation Charging Time under Lower Input Voltages scheme. In addition, the MP2624 supports USB On-The-Go operation by supplying 5V with High Accuracy of Charging Parameter 2 current up to 1.3A IC Port for Flexible System Parameter . Setting and Status Reporting The power path management regulates the Full DISC Control to Support Shipping Mode system voltage slightly above the set maximum High Integration 2 voltage between the battery voltage and the I C o Fully Integrated Power Switches and programmable lowest voltage level (e.g. 3.6V). No External Blocking Diode and Sense With this feature, the system is able to operate Resistor Required even when the battery is depleted completely or o Built-In Robust Charging Protection removed. When the input source current or including Battery Temperature Monitor voltage limit is reached, the power path and Programmable Timer management reduces automatically the charge o Built-In Battery Disconnection Function current to meet the priority of the system power High Accuracy requirement. If the system current continues o 0.5% Charge Voltage Regulation increasing, even when the charge current is o 5% Charge Current Regulation reduced to zero, the supplement mode allows o 5% Input Current Regulation the battery to power both the system and the o 2% Output Regulation in Boost Mode input power supply at the same time. Safety The MP2624 is available in a QFN-22 o Battery Temperature Sensing for 3mm x 4mm package.
