MP5505 7V, 4A, High-Efficiency Energy Storage and Management Unit The Future of Analog IC Technology FEATURES DESCRIPTION Wide 2.7V-to-7V Operating Input Range MP5505 is a lossless energy storage and Input Current Limiter with Integrated 60m management unit targeted at the solid-state and MOSFET hard-disk drive applications. Its highly-integrated input-current limit and energy storage and Up to 4.5A Input Current Limit release management makes the system solution Reverse Current Protection very compact. 6V Bus Clamping Voltage Power-On-Reset The internal input-currentlimit block with dv/dt Adjustable dv/dt Slew Rate for Bus Voltage control prevents inrush current during system Start-Up start up. The bus voltage start-up slew rate is Internal 30m Disconnect Switch programmable. It also includes a Power-On- Internal 70m and 60m Power Switches for Reset function for hot-swapping. MPSs patented Energy Storage and Release Management energy storage and release management control Circuits circuit minimizes the storage capacitor Thermal Protection requirement. It pumps the input voltage to a EN and Power-Good Indicators higher storage voltage and releases the energy over a hold-up time to the system in the case of Available in a QFN20 (3mm4mm) Package an input outage. The storage voltage and the APPLICATIONS release voltage are both programmable for different system applications. Solid-State Drives Hard-Disk Drives The MP5505 requires a minimal number of readily-available standard external components, Power Back-up/Battery Hold-up Supplies and is available in a 20-pin QFN (3mm4mm) All MPS parts are lead-free and adhere to the RoHS directive.
