MP2633 1.5A Single Cell Switch Mode Battery Charger with Power Path Management and Boost OTG The Future of Analog IC Technology DESCRIPTION FEATURES The MP2633 is a highly-integrated, flexible, 4.5V-to-6V Operating Input Voltage Range switch-mode battery charge management and Power Management Function Integrated system power path management device for a Input-Current Limit and Input-Voltage single-cell Li-ion and Li-Polymer battery used in Regulation a wide range of portable applications. Up to 1.5A Programmable Charge Current Trickle-Charge Function The MP2633 has two operating modescharge Selectable 3.6V/ 4.2V Charge Voltage with mode and boost modeto allow management 0.5% Accuracy of system and battery power based on the state Negative Temperature Coefficient Pin for of the input. Battery Temperature Monitoring When input power is present, the device Programmable Timer Back-Up Protection operates in charge mode. It automatically Thermal Regulation and Thermal Shutdown detects the battery voltage and charges the Internal Battery Reverse Leakage Blocking battery in the three phases: trickle current, Reverse Boost Operation Mode for System constant current and constant voltage. Other Power features include charge termination and auto- Up to 91% 5V Boost Mode Efficiency 1A recharge. This device also integrates both Programmable Output Current Limit for input-current limit and input-voltage regulation Boost Mode in order to manage input power and meet the Integrated Short Circuit Protection for Boost priority of the system power demand Mode In the absence of an input source, the MP2633 switches to boost mode through the MODE pin APPLICATIONS to power the SYS pins from the battery. The Sub-Battery Applications OLIM pin programs the output current limit in Power-Bank Applications for Smart-Phone boost mode. The MP2633 also allows an output Tablet and other Portable Device short-circuit thanks to an output disconnect feature, and can auto-recover when the short All MPS parts are lead-free and adhere to the RoHS directive. For MPS green circuit fault is removed. status, please visit MPS website under Products, Quality Assurance page. MPS and The Future of Analog IC Technology are registered trademarks of The MP2633 provides full operating status Monolithic Power Systems, Inc. indication to distinguish charge mode from boost mode. The MP2633 achieves low EMI/EMC performance with well-controlled switching edges. To guarantee safe operation, the MP2633 limits o the die temperature to a preset value 120 C. Other safety features include input over-voltage protection, battery over-voltage protection, thermal shutdown, battery temperature monitoring, and a programmable timer to prevent prolonged charging of a dead battery.
