8500 energy storage time shortened

Should energy storage systems be recharged after a short duration?

An energy storage system capable of serving long durations could be used for short durations, too. Recharging after a short usage period could ultimately affect the number of full cycles before performance declines. Likewise, keeping a longer-duration system at a full charge may not make sense.

What is the em8500 power management system?

The EM8500 is an autonomous power management system able to manage power domains, power sources and storage elements. At start-up the device enters a boot sequence. It controls the state of both energy storage elements, and sets the default configuration parameters of the device by retrieving the corresponding values from the on-chip E2PROM.

How does the em8500 maximize harvesting efficiency?

To maximize harvesting efficiency the EM8500 integrates a programmable maximum power point tracking controller. The EM8500 is capable of working with a variety of energy elements as secondary storage, namely re-chargeable batteries, super-capacitors or conventional capacitors.

Does the em8500 have a fast start-up capability?

In all cases the EM8500 maintains its fast start-up capability that depends only on the harvester conditions and the STS capacitor value. A USB connection to an external power source is available on the EM8500 for fast charge of the long term storage element.

How does the em8500 system shut-down work?

SYSTEM SHUT-DOWN The EM8500 informs the application when the available energy drops below a minimum level required for operation. After the first warning (through the VBAT_LOW pad), the device initiates an application shut-down sequence to protect the battery.

Does em8500 come in a 4x4 package?

The EM8500 is available in an industry standard QFN24 4x4 package as well as in bump form. Solutions or Applications The EM8500 is an integrated power management solution for low power applications.
