The latest mixed-signal controllers combine the best of both the analogue and digital power-conversion worldsStephen Stella,Microchip TechnologySince the introduction of digital power conversion designershave had a clear choice between using analogue or digital for their designs. Each approach has its own distinct benefits as well as drawbacks, but the development of mixed-signal or hybrid controllers is making it possible for designers to combine the best of both power-conversion worlds.Analogue for performanceThe advantage of analogue power conversion is that it offers ... more

Using Digital Signal Controllers (DSCs) for sensorless control of Brushless DC (BLDC) motor control to bring this technology within reach of low-cost, mass applicationsCharlie Ice, Microchip TechnologyAs the technology of choice for many high- to mid-range systems, Brushless DC (BLDC) motors offer a constant or variable speed drive combined with high reliability and ease of control. The use of even a few Hall Effect sensors, however, adds to the total system cost which can take BLDC out of the reach ... more

Stephen Porter, Microchip TechnologyA state-of-the-art user interface used to be a couple of knobs on the front of a television screen giving the user the power to get out of their chair and adjust the volume and the channel. Now, users don’t even need to get off the sofa to control simulated surround sound or high-quality video.As appliances become more complex and users expect more from the user interface, designers are faced with increasingly complex decisions such as: what information ... more

Jonathan Dillon, Microchip TechnologyIntroductionIt is critical that replaceable or disposable accessories for medical devices have a method of proving that the correct accessory, or attachment, is being used. If incorrect accessories are accidentally used, such as accessories designed for another model of the same equipment, or for another manufacturer’s equipment, thiscould cause safety issues. Furthermore, the reuse of disposable accessories may result in inferior performance and is likely to be unsanitary. Counterfeit accessories also pose a serious threat as they ... more

Ralf Hickl, Rutronik Elektronische BauelementeAnyone wanting to expand an existing device to include wireless technology usually connects a transceiver to the microcontroller. It sounds simple, but it isn’t. It requires recalculations regarding cost, quality and risk ratings, development and logistics costs increase and the reliability of the device often drops. Reason enough to consider a microcontroller with integrated transceiver. Many MCU manufacturers have already responded to the wireless trend and the growing demand for transceivers, supplying their chips with different ... more

Implementing MCUs which combine graphic display controllers, with support for capacitive-touch, touch-screen and USB peripherals.Rishi Vasuki, Microchip TechnologyHMI designs in embedded systems are evolving fast as the cost of manufacturing fashionable and more elegant interfaces continues to decrease. Some applications are already combining touch-sensitive interfaces, such as keys, sliders, touch-screens and haptic feedback, with rich graphical displays using the latest generation of microcontrollers (MCUs) which integrate graphic display controllers, with peripherals for implementing capacitive-touch, touch-screen controllers and USB onto a ... more
