MP2617 3A Switching Charger with NVDC Power Path Management For Single Cell Li+ Battery The Future of Analog IC Technology DESCRIPTION FEATURES The MP2617 is a monolithic switch mode 4V to 14V Operating Input Voltage battery charger with power path management Smart Power Path Management for single-cell Li-ion batteries in a wide range of Five Control Loops: Input Current Limit, tablet and other portable devices. It integrates a Input Voltage Limit, Constant Charge synchronous BUCK regulator to provide Current, Terminal Battery Control and regulated voltage for powering the system Thermal Fold-Back. output and at the same time charging the 1.6MHz Switching Frequency battery. This device supports both USB and Programmable Input Current Limit high power DC adapter input. In USB mode, the Programmable Charge Current input current limit can be programmed to Single Input for USB and AC adapter 450mA or 825mA via the logic pins to cover the Cover USB2.0 and USB3.0 Input USB2.0 and USB3.0 specifications. When the Specification adapter input is present, the input current can Fully Integrated Power Switches also be limited in order to avoid overloading of No External Blocking Diode and Sense the DC adapter. Input current limit can be Resistor Required programmed up to 3A. Charging Operation Indicator The smart power path management allows Built-in Programmable Charging Timer MP2617 to regulate the system voltage for Thermal Limiting Regulation on Chip powering an external load and charging the Battery Temperature Monitor battery independently and simultaneously. This Tiny Package Features Small Size. allows immediate system operation even under missing or deeply discharged battery. When the APPLICATIONS input current limit is reached, the system load is Smart Phone satisfied in priority, then the charger will take E-Book the remaining current to charge the battery. GPS Additionally, the smart power path control Portable Media Player allows an internal connection from battery to the Portable Hand-held Solution system in order to supplement additional power Tablet PC to the load in the event the system power demand increases over the input limited power All MPS parts are lead-free, halogen free, and adhere to the RoHS directive. For MPS green status, please visit MPS website under Quality or the input is removed. Assurance. MPS and The Future of Analog IC Technology are Registered The MP2617 features high integration with all Trademarks of Monolithic Power Systems, Inc. the power switches included inside. No external MOSFET, blocking diodes, or current sense resistor is required. Two status monitor output pins are provided to indicate the battery charge status and power source status. Other features include trickle charge, battery temperature monitoring, timer and thermal limiting regulation on chip. MP2617 is available in QFN 3mmx4mm package.
