MOSFETS feature low on resistance for high power density

May 10, 2022 By Redding Traiger

STMicroelectronics’ STPOWER MDmesh M9 and DM9 N-channel super-junction multi-drain silicon power MOSFETs are ideal for switched-mode power supplies (SMPS) in applications from data-center servers and 5G infrastructure to flat-panel televisions. The first devices to be launched are the 650V STP65N045M9 and the 600V STP60N043DM9. Both have very low on-resistance (RDS(on)) per unit area, which maximizes power density and permits compact system dimensions. Each has the […]

Relays designed for higher reliability in isolated high-voltage environments

May 10, 2022 By Aimee Kalnoskas

Building on more than two decades of experience developing new isolation manufacturing technologies and integrated circuits (ICs) for high-voltage systems, Texas Instruments introduced new portfolio of solid-state relays, including automotive-qualified isolated drivers and switches, that deliver industry-leading reliability to help make electric vehicles (EVs) safer. The new isolated solid-state relays also provide the smallest solution […]

What is “orthogonal”? (Part 2): signal space

May 10, 2022 By Bill Schweber

The phrase and concept “orthogonal” is widely used in engineering, but it is also often misunderstood. The formal definition of orthogonal signals does not necessarily mean that they are unrelated or uncorrelated, although that is how the term is often used in casual “engineering speak.” Formally, two vectors are orthogonal if their dot product is […]

What is “orthogonal”? (Part 1): mechanical design 

May 9, 2022 By Bill Schweber

The phrase and concept “orthogonal” is widely used in engineering, but it is also often misunderstood. I was chatting the other day with a non-technical friend and said something like, “Oh, that won’t happen. Those two things are orthogonal.” My friend looked at me and replied with a “huh?” and he was right to do […]

Advanced global-shutter image sensor for affordable, reliable driver-monitoring safety systems

May 6, 2022 By Redding Traiger

STMicroelectronics is enhancing vehicle safety with its latest global-shutter image sensors for driver monitoring systems (DMSs). DMSs continually watch the driver’s head movements to recognize signs of drowsiness and distraction, enabling systems in the vehicle to generate warnings that can preserve the safety of occupants. Traffic agencies estimate that about 95% of road traffic accidents […]
