MP2632BGR-P

MP2632B All-In-One, 3A, Battery Charger with 3A Boost Current with Independent Torch-On and BATT UVLO Latch-Off Funtion DESCRIPTION FEATURES The MP2632B is a highly integrated, flexible, Up to 20V Sustainable Input Voltage switch-mode battery charger with system 4.65V to 6V Operating Input Voltage Range power-path management designed for single- Power Management Function, Integrated cell Li-ion or Li-polymer batteries for use in a Input Current Limit, Input Voltage wide range of applications. Regulation Up to 3A Programmable Charge Current The MP2632B can operate in both charge Trickle-Charge Function mode and boost mode to allow for full-system Selectable 4.2V / 4.35V / 4.45V Charge and battery-power management. Voltage with 0.5% Accuracy The MP2632B has an integrated VIN-to-SYS 4-LED Driver for Battery Fuel Gauge pass-through path to pass the input voltage to Indication the system. The pass-through path has built-in Automatic Turn-Off at Light Load over-voltage (OVP) and over-current protection Input Source Detection (OCP) and a higher priority over the charging Output Source Signaling path. Independent Torch-Light Control When the input power is present, the MP2632B Negative Temperature Coefficient Pin (NTC) operates in charge mode. The MP2632B for Battery Temperature Monitoring detects the battery voltage automatically and Programmable Timer Back-Up Protection charges the battery in three phases: trickle Thermal Regulation and Thermal Shutdown current, constant current, and constant voltage. Internal Battery Reverse Leakage Blocking Other features include charge termination and Integrated Over-Voltage Protection (OVP) auto-recharge. The MP2632B also integrates and Over-Current Protection (OCP) for both input current limit and input voltage Pass-Through Path regulation to manage the input power and Reverse Boost Operation Mode for System prioritize the system load. Power In the absence of an input source, the Up to 3.0A Programmable Output Current MP2632B switches to boost mode through PB Limit for Boost Mode to power SYS from the battery. In boost mode, Integrated Short-Circuit Protection (SCP) the OLIM pin programs the output current limit, and Output Over-Voltage Protection (OVP) and the MP2632B turns off at light load for Boost Mode automatically. The MP2632B also allows for Available in a QFN-26 (4mmx4mm) output short-circuit protection (SCP) to Package disconnect the battery completely from the load in the event of a short-circuit fault. Normal APPLICATIONS operation resumes once the short-circuit fault is Sub-Battery Applications removed. Power-Bank Applications for Smartphones A 4-LED driver is integrated for voltage-based Tablets and Other Portable Devices fuel gauge indication. Together with torch-light All MPS parts are lead-free, halogen-free, and adhere to the RoHS directive. For MPS green status, please visit the MPS website under control, the MP2632B provides an all-in-one Quality Assurance.
