Enabling The Next Generation Of Smarter Self-Navigating Robots Using Hybrid ToF Technology


Previous generations of robot vacuum cleaners have used a random pattern for cleaning that is inefficient and slow. Next-generation robots are much smarter and generate a map of the environment using sensors to localize themselves. This provides users with a floorplan of their home, from which the rooms and areas can be selected for cleaning or restricted from access. The new robots accomplish ... » read more

Optimized Drivetrain And New Semiconductor Technologies Enable The Design Of Energy-Efficient Electric Vehicles


The traction inverter is the core component of the drivetrain in all-electric vehicles, making it the most essential system: The device plays a crucial role in enabling efficient and sustainable electromobility since it directly influences the power output and significantly affects the vehicle’s dynamics. However, to develop efficient electric vehicles the integration of complementary sub... » read more

Build Battery-Free Smart Locks With NFC Energy Harvesting Technology


Today, battery-powered smart locks with shared access capabilities have become increasingly popular in both consumer and industrial access control applications. However, battery-related issues frequently arise in many use cases. For outdoor applications, fluctuating temperatures and extremes can significantly reduce battery life. Indoor applications, on the other hand, can incur high battery re... » read more

Your Path To Robust And Reliable In-Vehicle Networking


Automotive networking technology is evolving fast, driven by a number of key trends. With a continuously increasing quantity of cars on the road and rising fuel costs, demand for energy efficiency is steadily growing. Worldwide legislation is establishing ever-stricter caps on CO2 emissions. The spotlight is also on functional safety. With the ISO 26262 automotive standard increasingly moving i... » read more

How To Meet The IoT Security Requirements Of Today And Tomorrow


Governments around the world are creating Internet of Things (IoT) security legislation and regulations designed to keep users safe in an increasingly connected world. Connectivity is good and, in fact, great but bad things can happen to people with unprotected or poorly protected IoT devices. Failing to meet government regulations or guidelines may lead to the inability to sell products in a r... » read more

Usage Of Pulse-Edge Transformer In Secondary-Controlled Flyback Applications


As the demand for smaller form factors and higher energy efficiency for charger/adapter grows, the wide bandgap (WBG) device technology is gaining popularity. To use the potential of WBG and thus improve the power density and efficiency, the switching frequency levels of converters are in the order of 300 kHz to 400 kHz. The higher switching frequency also requires faster control or response ti... » read more

Usage Of Pulse-Edge Transformer In Secondary Controlled Flyback Applications


The pulse-edge transformer (PET) is used as a medium to transmit PWM pulses from a secondary-side controller, such as EZ-PD™ PAGxS, to a primary-side controller, such as EZ-PD™ PAGxP, for AC/DC applications targeting the power adapter segment. This article explains the advantages of PET over the conventional opto-coupler based approach. Click here to read more. » read more

The Touch-Sensing HMI In Wearable And IoT Devices


The touch-sensing human-machine interface (HMI) in wearable devices is a key element of their consumer appeal, providing a responsive, intuitive way to interact via touch buttons and sliders in devices such as earbuds and smart glasses, or via a small touchscreen in a smart watch. Competition in the market for these types of wearable device continually drives innovation. Manufacturers battle fo... » read more

5th Generation CAPSENSE Technology


Capacitive touch sensing is a familiar and popular way to implement sleek, attractive and intuitive human-machine interfaces (HMIs) in devices such as smartphones, tablets and automotive displays. Now many manufacturers operating elsewhere, including in the industrial automation and home appliance markets, are exploring ways to increase the appeal, usability and value of their products by re... » read more
