Good news! Two ADI solution products won the 2019 China IoT Technology Innovation Award

The "New Intelligent World" China IoT Conference was recently held in Shenzhen Nanshan Kexing Science Park. The conference was held by Electronics Fan Network in 2016 and has attracted more than 90% of semiconductor manufacturers worldwide to participate. It aims to unite the upstream and downstream industries of the Internet of Things to work together, work with more cross-border companies to develop Internet of Things business opportunities, and explore the construction of the Internet of Things industry chain ecosystem.

The China IoT Innovation Award presented at the conference aims to discover and recognize leaders in the IoT industry who have pioneering spirit and make outstanding contributions to enterprises, outstanding technologies with innovative value and far-reaching impact, and innovative products that have been highly concerned and recognized by the market and industry users in the past year. It is the most professional and influential industry award in China's IoT industry.

Traditional maintenance is generally preventive or corrective maintenance, which usually accounts for a large part of production costs. Now, using IIoT (Industrial Internet of Things) to monitor the health status of machines can help achieve predictive maintenance, allowing industry personnel to predict failures, thereby significantly saving operating costs. The machine health status monitoring solution proposed by ADI can improve factory productivity and efficiency, maximize machinery uptime, and accelerate the realization of Industry 4.0.

The LTC3108 is a highly integrated DC/DC converter ideal for harvesting and managing surplus energy from very low input voltage sources such as TEGs (thermoelectric generators), thermopiles and small solar cells. The boost topology employed in the device operates normally with input voltages as low as 20mV.

Traditional DC/DC requires a certain starting voltage, which is usually not less than 700mV. However, the energy level of the space energy field is usually very low. Not only is the current weak, but the voltage level is usually not high either. For solar cells with the highest single voltage, the direct sunlight voltage of each unit does not exceed 600mV. Therefore, traditional DC/DC circuits cannot directly obtain the necessary working conditions from the weak energy of ordinary transducers.

ADI's technical experts are committed to exploring and breaking through limits, and have launched a voltage converter that only needs 20mV to start working. It can be used in conjunction with TEG thermoelectric transducers, single solar cells, etc. to achieve energy acquisition and voltage stabilization functions of IOT devices.

As shown in the picture, the space energy field is very weak

LTC3108 pioneered the introduction of an ultra-low voltage self-resonant circuit at the voltage absorption end. Together with a micro-transformer of about 1:50, it can reduce the weak energy source of no less than 20mV at the input end and amplify it to more than 1V, thereby driving a micro-power DC/DC voltage converter to form a stable output voltage at the common 3.3V, while providing a 2.2V LDO system maintenance voltage and energy storage management of about 5V.

The pioneering ideas and work of the ADI power team have enabled maintenance-free operation of IoT nodes in detection and sensor networks in environments with a temperature difference of 10°C to 20°C, providing innovative solutions:

In addition to TEG, LTC3108 is also suitable for other weak energy sources exceeding 20mV, thereby providing a stable micro-power voltage to power IoT sensor nodes for maintenance-free power supply.
