Energy harvesting Bluetooth LE switch reference design

ON Semiconductor has introduced a Bluetooth Low Energy Switch reference design, based upon the company’s RSL10 System-in-Package (SIP), that operates entirely from harvested energy.

The Energy Harvesting Bluetooth Low Energy Switch combines the low-power RSL10 SIP with the innovative energy-harvesting technology developed by ZF Friedrichshafen AG, to provide a platform for a range of IoT applications. The reference design also features a fully-integrated antenna, RSL10 radio, and all passive components.

The Switch reference design is provided with complete BoM, schematics, PCB layout and Gerber files, as well as free use of the switch-side firmware. The source code included a platform from which to develop application code, and the documentation includes detailed explanations of how to customize the firmware and connect the reference design to a Bluetooth Low Energy scanner application running on a smart phone or tablet. Exclusive new features of the switch include the absence of a buck/boost converter for simplified design-in and improved performance, as well as a smart dimming function.

The technology developed by ZF captures the energy transferred when a user presses a button. The switch converts energy from kinetic to electromagnetic, and stores it for use by the RSL10 SIP. Each time the button is pressed the fully integrated energy harvesting solution generates 300 μJ. This is enough to meet the extremely low power requirements of the RSL10 SIP, which is just 62.5nW in deep sleep and only 10 mW when transceiving.
