Autonomous Vehicles Deliver Advanced Safety and Convenience

2 weeks ago | electronicdesign.com | Ernest Worthman

The rise of autonomous vehicles (AVs) is poised to redefine the transportation landscape. In the transition from a futuristic concept to everyday reality, these driverless cars will have far-reaching effects on how the driver will interact with them. Eventually, once the glamor wears off, to be accepted by the masses, AVs will need to provide an experience as seamless as using your smartphone.
Reliable Energy Storage Creates a More Sustainable Future

1 month ago | electronicdesign.com | Ernest Worthman

The chemistry of choice has become lithium iron phosphate (LiFePO4) because of its many advantages, safety, long cycle Life, thermal stability, high discharge rates, and environmental friendliness. Coupled with the latest sensing and power-management technologies, they help create a top-tier solution that takes high-voltage, energy storage systems to the next level-safely and reliably. This technology presents in the form of advanced battery-management systems.
Deliver More Power to EVs with 48-V Systems

Such an architecture replaces mechanical sensors, activators, and fuses with semiconductor-based devices. Now, wiring networks have become communication networks. Turning Dumb into SmartWhile the upgrade to digital versions of relays, sensors, and fuses is a discussion unto itself, space is limited here, so fuses will be used as an example. Of course, smart fuses maintain the primary function of opening the circuit.
Reap the Rewards of Open-Source Software

Software AdaptabilityAdaptability in software is of monumental importance. This enables designers to create or add new features and functions by modifying the code. As long as designers adhere to the code's parameters, there will be no errors. This works at any stage of design or production, even the final product. A prime example of this is the software-defined vehicle (SDV). Today's vehicles have a diverse manufacturing base with thousands of vendors.
Creating the Immersive Automotive Audio Experience

Mar 5, 2025 | electronicdesign.com | Ernest Worthman

From car audio's fledgling beginnings in the 1930s as a simple AM in-dash noise source to today's fully immersive, multi-speaker, hundreds (even thousands) of watt theater-like environment, it's been a remarkable journey. Early high-end automotive audio was a niche market driven by a handful of audiophiles seeking to bring a much better sound experience to the wheeled environment. Eventually, as audio technology advanced, the niche audio market quickly adopted it.
"Auxless" GaN Flyback Converters Tackle AC-DC Adapter Design Challenges

Jan 8, 2025 | electronicdesign.com | Ernest Worthman

Another Tool for the EngineerThe TI auxless flyback converter is a great new tool for designers of the portable AC-DC power-supply market. The demands of some of the emerging and evolving devices require a much tighter, higher power, and smaller footprint regulated supply than transformer-based designs. Such is particularly true for supplies that provide variable outputs. The auxless converter is also an ideal solution for the next generations of AC-DC USB Type-C devices.
Meet the Latest Cybersecurity Standards with New, Integrated Wireless MCUs

Nov 21, 2024 | electronicdesign.com | Ernest Worthman

The evolution of devices with system-level security measures has reached critical mass. For example, TI's CC2745P10-Q1, CC2755R10, and CC3551E offer significant system-level security options based on authentication algorithms for key agreement, encryption, and exchange. These MCUs address not only BT, but Wi-Fi, Mesh, Zigbee, Matter, and others.
Exploring the Essential Role of Analog Technology

Oct 13, 2024 | electronicdesign.com | Ernest Worthman

As the digital transformation permeates deeply across so many industries, it's easy to forget that some things just work better in analog. And today, the analog world is still alive and thriving. A popular example of that is in the audio component world. Today's mass-market audio gear is built largely with digital circuits. Yet, peel back the layers of this platform and one can find a segment that still uses analog components-vacuum tubes, particularly.
Key Insights to Help Optimize 6G's Launch

Sep 25, 2024 | electronicdesign.com | Ernest Worthman

Trying to salvage some dignity, certain players started to slap labels on the hybrid systems; 5.5G, 5GE, or advanced (not the advanced stipulated in 3GPP rel. 18) were the main attempts. However, under the covers, it's still hybrid 4G. And there was quite a bit of grandiloquence over early 5G claims. On top of that, advanced iterations of 4G were still doing the job (a story for another time). The Next Chapter: 5G Progress and Emerging VerticalsOk, I think we get the picture.
Mid-Voltage Systems Turn to GaN Devices to Achieve the Highest Power Density

Apr 10, 2024 | electronicdesign.com | Ernest Worthman

The demand for mid-voltage power circuits in segments such as robotics, server farms, solar installation, RF, motor control, LiDAR, synchronous rectification, and more has put mid-range power efficiency on the map. No longer do engineers have the luxury of design first, power efficiency second. In fact, the holy grail of semiconductor and electronic devices, in general, is to squeeze as much power as possible using the smallest-possible footprint with the least amount of energy consumption.
