PCI Express Passes Other Standards Found in Automobile Entertainment Systems
Move over CANbus, PCI Express is the latest communications technology found in automotive infotainment.
Linear Redrivers Make Visible Difference in DisplayPort Connections
Capable of 10 Gbps speeds and beyond, DisplayPort requires linear redrivers to achieve proper signal integrity with link training.
Active Capacitor Discharge Circuit Considerations for FPGAs
The multiple power rails of today’s FPGAs and high-performance processors must be powered up and powered down in strict sequence. The decoupling capacitors normally attached to the power rails must be actively discharged, to ensure proper control of the power-down sequence and to complete power-down in an acceptable time. This article describes the principles and design of active discharge circuitry, and explains selection criteria for key components such as power MOSFETs to ensure repeatable performance and reliability.
LED Control Maximizes Benefits of Daylight Running Lamps
Daylight running lamps for motor vehicles are now a legal requirement in Europe. They became mandatory for new cars manufactured from February 2011 and for commercial vehicles from August 2012. Although they now need to be incorporated in vehicles by law, the daylight running lamp provides a number of opportunities for car and van designers to improve multiple aspects of the driving experience and their own brand image.
Self-Protecting MOSFETs Deliver Improved Reliability in the Harsh Environment of Automotive Applications
While it’s been said many times before, the automotive electrical environment is tough! As demonstrated in figure 1, the nominal battery voltage of an automobile can vary from -12V DC, under reverse battery condition, to +125V DC due to load transients and inductive field decay. Factor in wide variations in operating temperature, numerous interconnections and an open environment that is subject to possible ESD damage from human interactions, and you have an operating environment that is far more challenging than, for example, that of the consumer market segment.
Making Switches Smarter with True Micropower Hall Effect Sensors
Linear Hall effect sensors can bring valuable advantages to consumer technology and Internet of Things applications, but must achieve a significant reduction in power consumption in order to meet the expectations of equipment designers and end users
