MP5053 is a management IC specially designed for power bank, highly integrating switch charger, battery information display and synchronous boost output, with charging current up to 2A and synchronous boost output up to 2.4A. It also provides discharge path management, torch and other functions. MCU supports personalized settings of the output mode of LED lights, such as Ticker, BLN, Drop, or for applications in LED display, greatly simplifying peripheral circuits and components, and providing the simplest, low-cost solution for power bank applications such as large-capacity lithium battery (lithium ion or lithium polymer).
MP5053 is available in a ESOP8 package.
