MP2636 3.0A Single Cell Switch Mode Battery Charger with Power Path Management (PPM) and 3.0A System Boost Current The Future of Analog IC Technology DESCRIPTION FEATURES The MP2636 is a highly-integrated, flexible Up to 16V Sustainable Input Voltage switch-mode battery charger with system power 4.5V-to-6V Operation Voltage Range path management, designed for single-cell Li- Power Management Function, Integrated ion or Li-Polymer batteries used in a wide range Input-Current Limit, Input Voltage of portable applications. Regulation Up to 3.0A Programmable Charge Current The MP2636 can operate in both charge mode Trickle-Charge Function and boost mode to allow full system Analog Voltage Output IB pin for Battery management and battery power management. Current Monitor When input power is present, the device Selectable 4.2V / 4.3V / 4.35V Charge operates in charge mode. It automatically Voltage with 0.5% Accuracy detects the battery voltage and charges the Negative Temperature Coefficient Pin for battery in three phases: trickle current, constant Temperature Monitoring current and constant voltage. Other features Programmable Timer Back-up Protection include charge termination and auto-recharge. Thermal Regulation and Thermal This device also integrates both input current Shutdown limit and input voltage regulation in order to Internal Battery Reverse Leakage Blocking manage input power and meet the priority of the Integrated Over Current Protection and system power demand. Over Voltage Protection for Pass-through In the absence of an input source, the MP2636 Path switches to boost mode through the MODE pin Reverse Boost Operation Mode for System to power the SYS pins from the battery. The Power OLIM pin programs the output current limit in Up to 3.0A Programmable Output Current boost mode. The MP2636 also allows an output Limit for Boost Mode short circuit protection to completely disconnect Integrated Short Circuit Protection and the battery from the load in the event of a short Output Over Voltage Protection for Boost circuit fault. Normal operation will recover as Mode soon as the short circuit fault is removed. The MP2636 provides full operating status indication APPLICATIONS to distinguish charge mode from boost mode. In Sub-Battery Applications addition, the MP2636 can report the real battery Power-bank Applications for Smart-Phone, current in both charge and boost mode via IB Tablet and Other Portable Devices pin. All MPS parts are lead-free and adhere to the RoHS directive. For MPS green The MP2636 achieves good EMI/EMC status, please visit MPS website under Products, Quality Assurance page. MPS and The Future of Analog IC Technology are registered trademarks of performance with well controlled switching Monolithic Power Systems, Inc. edges. To guarantee safe operation, the MP2636 limits o the die temperature to a preset value of 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.
