EM8500
Description
The EM8500 is an integrated power management solution for low power applications. It is specifically designed for efficient operation with a variety of DC harvesting sources including thermal electric generators (TEG) or photovoltaic (solar) sources in the μW to m W range. The device is designed to speed-up system start-up time when the main energy storage element (aka Long Term Storage
- LTS) is pletely discharged or insufficiently charged to supply the application, by using a secondary energy storage element (Short Term Storage
- STS).
When using a non-rechargeable primary battery the EM8500's onboard PMU offers a mechanism to extend battery life when assisted by a harvesting element.
The EM8500 incorporates a boost converter able to start with an input voltage as low as 300 m V and an input power of few μW. In functional mode the EM8500 operates at energy levels from a DC harvesting source as low as 100 m V and 1 μW. To maximize harvesting efficiency the EM8500 integrates...
