MP2633A 1.5A Single Cell Switch Mode Battery Charger with Power Path Management and Boost OTG The Future of Analog IC Technology DESCRIPTION FEATURES The MP2633A is a highly-integrated, flexible, 4.5V-to-6V Operating Input Voltage Range switch-mode battery charge management and Integrated Input-Current-Based Power system power path management device for a Management Function single-cell Li-ion and Li-Polymer battery used in Up to 1.5A Programmable Charge Current a wide range of portable applications. Trickle-Charge Function Selectable 3.6V/ 4.2V Charge Voltage with The MP2633A has two operating modes 0.5% Accuracy charge mode and boost modeto allow Negative Temperature Coefficient Pin for management of system and battery power Battery Temperature Monitoring based on the state of the input. Programmable Timer Back-Up Protection When input power is present, the device Thermal Regulation and Thermal Shutdown operates in charge mode. It automatically Internal Battery Reverse Leakage Blocking detects the battery voltage and charges the Reverse Boost Operation Mode for System battery in the three phases: trickle current, Power constant current and constant voltage. Other Up to 91% 5V Boost Mode Efficiency 1A features include charge termination and auto- Programmable Output Current Limit for recharge. This device also integrates input Boost Mode current limit in order to manage input power and Integrated Short Circuit Protection for Boost meet the priority of the system power demand Mode In the absence of an input source, the MP2633A switches to boost mode through the APPLICATIONS MODE pin to power the SYS pins from the Sub-Battery Applications battery. The OLIM pin programs the output Power-Bank Applications for Smart-Phone, current limit in boost mode. The MP2633A also Tablet and other Portable Device allows an output short-circuit thanks to an output disconnect feature, and can auto-recover All MPS parts are lead-free and adhere to the RoHS directive. For MPS green when the short 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 MP2633A provides full operating status Monolithic Power Systems, Inc. indication to distinguish charge mode from boost mode. The MP2633A achieves low EMI/EMC performance with well-controlled switching edges. To guarantee safe operation, the MP2633A limits the die temperature to a preset value o 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.
