Mouser Electronics becomes first authorised global distributor of e-peas energy-harvesting PMICs

With products that help design engineers enable their hardware to be powered indefinitely, e-peas provides IC solutions for applications such as industrial, home and building automation, agriculture, health monitoring, smart metering and other sectors. The e-peas Ambient Energy Manager (AEM) product line, available from Mouser, includes solar, thermal, vibration and RF methods for extracting energy to supply Internet of Things (IoT) devices.

The company’s energy-harvesting ICs are integrated energy management circuits that extract power from a harvester to simultaneously store energy in a rechargeable element and to supply the system with two independent regulated voltages. The ICs harvest the available input current up to 110 mA, and integrate an ultra-low-power boost converter that operates with input voltages in a range from 50 mV to 5 V. With their unique cold-start circuit, they can start operating with empty storage elements at an input voltage as low as 380 mV (50 mV for thermal applications) and an input power of just 3 µW.

The AEM10941 solar energy-harvesting IC extracts DC power from up to seven-cell solar panels, while the AEM20940 thermal energy-harvesting IC extracts DC power from a thermoelectric generator (TEG). The AEM30940 RF energy-harvesting IC can extract DC power from a piezo generator, a micro turbine generator, or any other high-frequency RF waves at 868 MHz or 915 MHz with a minimum input power of 19 dBm and at 2.4 GHz with a minimum input power of 14 dBm. The AEM40940 RF energy-harvesting IC extracts AC power from ambient RF waves, harvesting the available input power from 20 dBm up to 10 dBm.
