MP2617H Wide input Voltage, 3A, Switching Charger With NVDC Power Path Management For Single Cell Li+ Battery DESCRIPTION FEATURES The MP2617H is a monolithic, switch-mode, 4V to 14V Operating Input Voltage battery charger with power path management for Smart Power Path Management single-cell Li-ion batteries in a wide range of Five Control Loops: Input Current Limit, tablets and other portable devices. The Input Voltage Limit, Constant Charge MP2617H integrates a synchronous buck Current, Terminal Battery Control, and regulator that provides regulated voltage to Thermal Fold-back power the system output and charge the battery 1.6MHz Switching Frequency simultaneously. The MP2617H supports both Programmable Input Current Limit USB and high-power DC adapter inputs. In USB Programmable Charge Current mode, the input current limit can be programmed Single Input for USB and AC Adapter to 450mA or 825mA via the logic pins to cover Covers USB2.0 and USB3.0 Input USB2.0 and USB3.0 specifications. When the Specifications adapter input is present, the input current can Fully Integrated Power Switches also be limited to avoid overloading the DC No External Blocking Diode or Sense adapter. The input current limit can be Resistor Required programmed up to 3A. Charging Operation Indicator Smart power path management allows the Built-In Programmable Charging Timer MP2617H 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 Available in a QFN-20 (3mmx4mm) allows for immediate system operation, even Package under missing or deeply discharged battery conditions. When the input current limit is APPLICATIONS reached, the system load is satisfied first, and Smartphones then the charger uses the remaining current to E-Books charge the battery. Additionally, the smart power GPS path control allows for an internal connection Portable Media Players from the battery to the system to supplement Portable Handheld Solutions additional power to the load in the event the Tablet PCs system power demand increases over the input- limited power or the input is removed. All MPS parts are lead-free, halogen-free, and adhere to the RoHS directive. For MPS green status, please visit the MPS website under Quality The MP2617H features high integration with all Assurance.
