Circuits & Schematics - Automotive

In the automotive industry, in which the goal is to produce cars with simpler, lighter wiring looms, any interface that uses just one wire instead of two offers a distinct advantage. The circuit in Figure 1 implements a bidirectional link using a ...

Engineers often face difficult trade-offs when voltage regulators can encounter high-voltage transients that are well above normal input-supply operating ranges. This situation is common in automotive applications in which high-voltage transients ...

I was using a thermoelectric cooler for a camping trip and discovered the next morning that my car battery was dead from the load. I never expected a 3.5-A load to drain the battery in eight hours. So I went about making a circuit that could be ...

Ajay R. Dandge Electronic Design In microcontroller-based embedded systems, it is imperative to provide a means of triggering system reset to take care of software runaways. Many such remedies involve the implementation of an external watchdog ...

The LT8711 is a DC/DC controller that supports synchronous buck, boost, SEPIC and ZETA topologies, or nonsynchronous buck-boost topologies. Analog Devices offers numerous synchronous buck and boost converters and regulators, but the synchronous ...

Environmental concerns are spurring the development of clean transportation alternatives. Most popular are full electric and hybrid electric motor vehicles, which use stacks of lithium-ion battery cells as the electric power source. To ensure ...

Figure 1 shows a power supply that delivers 5 V from a 12 V battery. With only a few components, the supply copes with all the automotive transients that ISO (International Organization for Standardization) 7637-1 lists without the need for a bulky ...

Mike Shriver, Linear Technology Design Note 543 The LTC7138 is a 400 mA step-down regulator that can operate over an input voltage range of 4 V to 140 V, ideal for industrial, telecom, automotive and other applications subject to harsh line ...

Michael Page EDN The circuit in Figure 1 is not complex, but it saved the day in an application involving visual inspection of the spray pattern of fuel injectors for quality and consistency. In this application, xenon strobe lights did not work ...

Charlie Zhao, Linear Technology Design Note 512 Introduction The trend in automobiles and industrial systems is to replace mechanical functions with electronics, thus multiplying the number of microcontrollers, signal processors, sensors, and other ...
