Piezo sounders create warning or alert noises in many applications, oftentimes in portable, battery-powered, and space-saving products. These devices consist of a ceramic element attached to a metal plate, where the ceramic element uses the piezoelectric effect to distort its shape when a voltage is applied. As it contracts and expands due to the varying voltage, the attached plate vibrates audibly.
The automotive lighting market continues to grow strongly and is forecast by analyst Yolé to reach US$38.8 billion by 2024. Over the past few years, LEDs have taken an increasing share of this market, and LED exterior lights have become a familiar sight on our roads.
The global appetite for data shows no sign of abating and continues to place pressure on service providers to handle more bits, more quickly.
DC electric motors have been around for nearly two hundred years, with a steady series of refinements in that time. More recently, brushless DC motors have become increasingly popular but for many applications brushed DC motors are still the right choice.
Fibre optic networks bring the promise of fast broadband to new customers all around the world. It increasingly reaches new limits, but to provide a guaranteed level of service, that bandwidth must be managed effectively. A significant factor to that effectiveness is how it interfaces with other network equipment running over copper cable.
Highly integrated solutions for USB 3.2 data switching, USB Power Delivery and USB Battery Charging control, and transient protection help designers unleash the full potential of the USB Type-C interface.
In automotive applications, it’s essential to protect sensitive semiconductor components against power surges, transients and electrostatic discharge (ESD). A single transient voltage spike could easily damage or disrupt a component, while electrical noise of even relatively low energy can cause significant interruption to digital communications.
For the design of almost any electronics or electrical system, it’s important to maximise power efficiency. In mobile devices, better power efficiency delivers longer battery life, which is a key selling point. For basically any application, improving power efficiency means that size and weight can be reduced, and thermal management simplified – thus reducing costs. Of course, using less power also helps products to meet energy rating requirements, which may be a legal requirement, and an attractive feature for customers.
The ‘perfect storm’ of high bandwidth internet connectivity, deep learning algorithms and high-quality audio is enabling a new paradigm in user interfaces: the spoken word. The ability to interact with household appliances and cloud-based services through natural language is truly a sea-change in the way people and machines interact.
