EHR5334S is an integrated single chip energy harvesting solution from STMicroelectronics. This chip is designed to optimize energy harvesting from multiple sources, such as solar panels, vibration, thermal, and air flow. It features a dedicated dynamic control loop for managing transduction paths, a charge pump, a switch mode step-up boost converter, and a Direct Path Regulator to maximize power transfer from the energy harvester.
This single chip solution enables designers to create highly efficient systems for capturing and harnessing ambient energy. It supports several popular Energy Harvesting buses (EH-bus) such as I2C and SPI. It is qualified with automotive temperature and operating range, making it suitable for a wide range of applications. The device also features an advanced anti-theft protection mechanism for preventing unauthorized access to the system data.
