MP5046 is a single-chip IC specially designed for power bank, highly integrating switch charger, LED battery display cell and synchronous boost output, with charging current up to 2A and synchronous boost output up to 2.4A. It also provides discharge path management, battery display, torch, 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).
MP5046 is available in a ESOP8 package.
