A bad connection or open circuit between the alternator output terminal and the positive battery terminal will force the charging current to follow a parallel route through the diode trio and out of the alternator. This heavier than normal current flow through the diodes will cause them to overhea...

Figure 1 provides a top-level view of a complete automotive TFT display system. The very first step in designing one is to establish system requirements, such as display power supply needs, display video format, and system input voltage operating range. A good start would be to go th...
Previously, the most troublesome aspect of using projectors was the diminishing performance of bulbs. When it came time to use a projector, one had to quickly turn off the lights and close the curtains. Although LED (light-emitting diode) light sources appeared, their efficiency was also low. ...
The automotive industry is forging ahead with the development of a variety of automotive applications to ensure road safety and enhance driver’s in-vehicle experiences. Advanced driver-assistance systems (ADAS) are an example of these. ADAS and...
Measuring the Voltage Generated by Light on an LED Step 8:Now switch your multimeter to the lowest DC voltage range available, and touch the meter’s test probes to the terminals (wire leads) of the light-emitting diode (LED) as illustrated in Figure 4. A LED is designed to produce ligh...
HID (High-Intensity Discharge) lights use gas to produce light. An electrical charge ignites the gas and creates a high-intensity light. HIDs are brighter than halogen and produce white or blue light. LED (Light Emitting Diode) lights use semiconductors that emit light when an electrical current...
AN5084 Application note How to improve EMI behavior in switching applications Introduction The aim of this application note is to provide the criteria to improve EMI behavior in automotive switching applications. The present analysis helps understanding why EMI is critical in switching appli...
For instance, automotive load dump can occur when the alternator (charging the battery) is momentarily disconnected from the battery. As a result of this disconnect, the full charge current from the alternator is placed on the power rail, which raises the rail voltage to very high (>100 V)...
