DATASHEET Ɩ EM8502 POWER MANAGEMENT CONTROLLER WITH MULTI-CELL SOLAR HARVESTING Description The EM8502 is an integrated power management solution for low power applications. It is designed to simplify the design of application using multiple solar cells in series that can be directly connected to the application and storage elements. The device is designed to speed-up system start-up time when the main energy storage element (aka Long Term Storage – LTS) is completely discharged or insufficiently charged to supply the application, by using a secondary energy storage element (Short Term Storage - STS). When solar energy is high enough the device connects the solar cell to STS or LTS to maintain the supply of the application, while charging the rechargeable element.
