The EHM-UNIV, says the company, is a small surface-mount energy harvesting and power management module that eliminates the need for engineers to purchase energy harvesting evaluation modules, and determine how to engineer power management ICs into their application. The module is designed to capture small amounts of harvested energy from sources such as photovoltaic cells, piezoelectric, electro-mechanical and thermoelectric generators, and continuously trickle charge storage elements like rechargeable Li-Ion batteries, thin-film batteries, or conventional capacitors.
The module, says the company, simply allows an IoT device developer to connect their energy harvesting generator into the device and their supercapacitor/battery to the output – no engineering required.
“There are multiple power management ICs for energy harvesting from great companies,” says David Ambrose, Director of engineering, “but they all require significant external power engineering to determine how to condition the energy harvesting generator input, protect the IC and then manage and protect the outputs, either directly or via a supercapacitor or rechargeable battery. At Xidas, we have done the engineering, packaged it in a small SIP module. We feel it should be as simple as selecting your solar, thermal, electromechanical vibration or piezoelectric generators, plugging them into an energy harvesting module and hooking it up to the output.”
The EHM-UNIV comes equipped with built-in rectification circuitry, enabling users to easily choose whether to connect an AC or DC energy harvesting source; active overvoltage protection for the energy harvesting circuitry; and a tunable regulated output or unregulated system output conditioned for powering virtually all wireless IoT sensors. The module also has a wide operating temperature range from -40°C to +85°C, and significant power monitoring for IoT battery feedback.
Pricing for the module is $45 (10-99 qty).
