Suitable for a broad array of potential use cases, including industrial control/monitoring, building automation, smart homes, agriculture, environment monitoring, healthcare and smart metering, e-peas technology is already being widely deployed. The company’s Ambient Energy Manager (AEM) PMIC series offers effective solutions that are specifically optimised for solar, thermal, vibration and RF oriented energy harvesting. By using these devices, IoT hardware can be powered indefinitely, without the need to periodically replace batteries.
The AEM series includes:
- The AEM10941 - This solar energy harvesting PMIC is capable of extracting DC power from photovoltaic cells, covering 380mV to 3µW.
- The AEM20940 - Which is dedicated to thermal energy harvesting, and can manage DC power from 60mV, taken off thermo-electric generator (TEG) outputs.
- The AEM30940 - For use in situations where vibrational-based energy harvesting is applicable, this PMIC (combined with an adapted rectifier) can deal with the DC power provided by piezo generators, micro turbine generators or RF antennas.
- The AEM40940 - This energy harvesting PMIC extracts AC power from ambient RF waves, leveraging the available input power from 20dBm up to 10dBm.
These PMICs extract power from their respective harvesters as soon as the 380mV and 3µW threshold is met. Due to their cold-start circuitry, operation can be initiated with empty storage elements from a far lower input power than for competing devices.
They can then supply this power to IoT hardware via 2 independent regulated voltages lines (thanks to the 2 LDOs integrated), delivering currents of up to 80mA and simultaneously store the extracted energy in rechargeable elements (such as battery cells or supercapacitors).
Each PMIC has a built-in ultra-low power boost converter that operates with input voltages of between 50mV and 5V. Furthermore, only a small number of passive components are required to accompany these PMICs, thereby saving board space and keeping bill of materials costs down.
“Through this new supply chain partnership with Mouser, e-peas will be able to address a much wider prospective market. It will mean that our technology is more accessible than ever before,” said Christian Ferrier, CMO of e-peas.
