Industry 4.0 was a term coined in 2011 at the Hannover Fair and refers to the fourth industrial revolution. Taking place as far back as the late 18th Century, the first industrial revolution related to the mechanisation of manufacturing. This led to electrification in the early part of the 20th Century (the second industrial revolution).

Computerisation and automation ushered in the third industrial revolution during the 1980s with advancements such as the PC, the internet and information and computer technology (ICT).

The fourth industrial revolution builds on the digital revolution, representing new ways in which technology becomes embedded within different sectors. It is causing a period of rapid change within manufacturing as the industry moves from automated production to full digitisation.

Within Industry 4.0, digital communication forms the backbone of a networked production system. Additional sensors for condition monitoring in gearboxes, rolling bearings and motors optimises the service life of systems and machines, increases productivity and reduces down-time.

The networking of automation systems with the internet increases the transparency of production systems and allows new business models to analyse and process large amounts of data.

To achieve full digitalisation and reap the benefits of Industry 4.0, manufacturers will need the latest technologies in industrial communication, sensors and control. Texas Instruments offer a range of products to meet these needs including:

To maximise efficiency, the converter operates in PWM mode with a nominal switching frequency of 2MHz and automatically enters Power Save Mode operation at light load currents. In Power Save Mode, the device operates with typically 20µA quiescent current. Using the DCS-Control topology, the device achieves excellent load transient performance and accurate output voltage regulation.

TVS3300: The TVS3300 is a transient voltage suppressor which provides robust protection for electronic circuits exposed to high transient voltage events. Unlike a traditional TVS diode, the TVS3300 precision clamp triggers at a lower breakdown voltage and regulates to maintain a flat clamping voltage throughout a transient overvoltage event.

The lower clamping voltage combined with a low dynamic resistance enables a unique TVS protection solution that can lower the voltage a system is exposed during a surge event by up to 30% in unidirectional configuration and up to 20% in bidirectional configuration when compared to traditional TVS diodes. The low clamping voltage and flat clamping performance allow designers to confidently select downstream system components with maximum voltage rating than is possible with traditional TVS diodes, saving system cost, board area and improving overall performance.
