Energy harvesting power management IC addresses wireless sensors

August 20, 2015 //By Julien Happich
Cypress Semiconductor has released a family of Energy Harvesting Power Management Integrated Circuits (PMICs) that enable tiny, solar-powered wireless sensors for Internet of Things (IoT) applications.

The devices are claimed to be the world's lowest-power, single-chip Energy Harvesting PMICs, and can be used with solar cells as small as 1 cm 2. The new PMIC devices are fully integrated, making them suitable for battery-less Wireless Sensor Nodes (WSNs) that monitor physical and environmental conditions for smart homes, commercial buildings, factories, infrastructure and agriculture.

Cypress offers a complete, battery-free Energy Harvesting solution that pairs the S6AE101A PMIC, the first device in the new family, with the EZ-BLE PRoC module for Bluetooth Low Energy connectivity, along with supporting software, in a USD 49 kit.
The PMIC devices support a startup power of 1.2uW, about four times lower than the nearest competitor, and a consumption current as low as 250nA, maximizing the power available for the sensing, processing and communications functions of a target application.

The S6AE101A PMIC is sampling now, with production expected in the fourth quarter of 2015. Solar-Powered IoT Device Kit contains a baseboard with a solar module and a Bluetooth Low Energy-USB bridge.
