ET95641
ET95641 General Description
The ET95641 is specifically designed to extract DC energy harvesting, high-impedance sources like photovoltaic(solar) or thermal electric generators (TEGs) without collapsing those sources. 5V input Linear Charger can also be used to charge the battery (e.g. if the battery gets depleted). This fully integrated and compact power management system allows for extending battery lifetime and eliminating the primary energy storage in a large range of applications.
The ET95641 has a built-in cold-start circuit, it can start operating with an input voltage as low as 275mV(min.5µW power), it makes ET95641 to better harvest the energy from those energy harvesting.
There is a boost from the energy harvesting to the battery. The boost can implements voltage regulation of the energy harvesting, allowing for harvesting the maximum efficiency energy harvesting from the source to the battery.
There is a buck regulator with selectable output voltage from the battery which allows an application circuit to be supplied with high efficiency.
ET95641 has abundant analog and digital configurable resources to meet the requirements of various customized functions.
ET95641 can work in shipping mode which can avoid charging and discharging of the storage element during shipping or storage.
