electronica 2008 - ON Semiconductor - energy-efficient solutions for automotive, industrial and portable designs with live stand demonstrations

For the automotive sector, demonstrations will show the application of the company’s mixed-signal bridge driver technology in a throttle design and the use of ON Semiconductor devices in door mirror and HVAC systems. Twice a day during the show visitors will also have the opportunity to enter a competition to achieve the shortest time for accurately parking a remote controlled car that has been equipped with an ON Semiconductor ‘park assist’ sensor.

Industrial motor control demonstrations will be based on the ON Semiconductor family of mixed-signal motor driver ICs that combine integrated networking with high levels of functionality. One will show a LIN-enabled device controlling three motors on a LIN network and another will illustrate CAN- and I2C alternatives. These demonstrations will illustrate benefits such as simplicity of networking and ease of implementation as well as key features such as stall detection and automatic reset functionality.

Demonstrations for portable applications will include a display & lighting subsystem that shows how the recently announced NCP5890 lighting management IC can be used to control LED lighting in devices such as mobile phones. In the demonstration the device is used to control a combination of white backlighting LEDs and RGB LEDs, highlighting its ability to provide LED dimming and audio modulated ‘fun’ lighting responses. Electronica will also see the European debut of the ON Semiconductor NCP5680 flash LED driver IC in a power management subsystem where this device in conjunction with a super-capacitor (supercap)functions as a peak load delivery IC. It will be used to drive two high-current LEDs and Class D stereo audio amplifiers, illustrating how the NCP5680 can contribute to overall system power reductions.

Further benefits of using ON Semiconductor technology in LED-based applications will be illustrated in a demonstration that compares the power efficiency of two identical desk lamps, one with an incandescent bulb and one with an LED and ON Semiconductor LED Driver. In addition, a prototype 60W green power supply for an LCD monitor will show how PSU designers can use ON Semiconductor technology to meet and exceed power conservation targets.

Finally, in line with the company’s strategy to deliver high-performance audio solutions to portable applications, ON Semiconductor will also have an audio subsystem demonstrator based on its BelaSigna 250+ ultra-low-power audio processor technology. This demonstration will highlight key functions including voice enhancement, noise cancellation, bass enhancement and dynamic range processing.
