MP2611GL-P Monolithic Power Systems

MP2611 2A, 1-Cell Li-Ion Battery Switching Charger For USB and Adapter Power The Future of Analog IC Technology DESCRIPTION FEATURES The MP2611 is a monolithic switching charger 4.5V-to-6V Operating Input Voltage with built-in power MOSFETs for a single-cell Up to 100% Duty Operation. Li-Ion battery pack. It achieves up to a 2A- Up to 2A Programmable Charge Current charge current that can be programmed 0.5% Battery Voltage Accuracy through an accurate sense resistor over the Separate Inputs for USB and AC Adapter whole input range. It can operate from separate Fully-Integrated Power Switches inputs for USB or AC adapter: For USB input, Programmable Input Current Limit for the the input current limit can be programmed to USB Port 500mA and 900mA through the USBM pin to No External Reverse Blocking Diode cover both USB2.0 and USB3.0 standards. Required The MP2611 regulates the charge current and Charging Operation Indicators battery voltage using two control loops to Programmable Safety Timer realize highly accurate constant-current charge Thermal Shutdown and constant-voltage charge. A 100% duty Cycle-by-Cycle Over Current Protection cycle can be achieved when battery voltage is Battery Temperature Monitor and Protection close to the input voltage due to the high-side P-Channel MOSFET. APPLICATIONS Battery charge temperature and charging status Smartphones are always monitored for each condition. Two Portable Hand-Held Solutions status-monitor output pins indicate the battery Portable Media Players charging status and input status. The MP2611 All MPS parts are lead-free and adhere to the RoHS directive. For MPS green also features internal reverse-blocking status, please visit MPS website under Products, Quality Assurance page. protection.
