Electronics for Automotive

Introduction   This post will help you understand methodology to design ESD (Electro Static Discharge) protection capacitors for Automotive application PCB's. Prerequisite : For People with understanding of ESD, Circuit design, Working in Electronics field/ pursuing Electronics degree. What is ESD  Electrostatic discharge (ESD) is the sudden flow of electricity between two electrically charged objects caused by contact, or Air, by an electrical short , or dielectric breakdown . What will happen if ESD protection is not implemented in PCB ?  Damage to the PCB due to ESD will be either Latent or Catastrophic. When a PCB or its components suffers latent damage due to ESD, it may be partly degraded, and continue to run. However, the device becomes unreliable as its lifetime reduces, and its operational behavior affected. Component damaged due to ESD Catastrophic damage occurs when the device is permanently damaged because of ESD. A performance test...

Introduction I would like to share few of the basics for designing sensor circuit input configuration for Automotive application, which can also be used for other applications such as Industrial applications with some adaptations.            To begin with, let me start by dividing commonly used sensors in Automotive into 3 types. 1) Analog Sensor 2) Digital Sensor 3) Frequency Sensor In this article lets concentrate on Analog & Digital Sensors. I will write a separate article for Frequency Sensors. Different types of Circuits on Sensor line:           A typical interface circuit between Sensor & Micro controller. You will understand the importance of each component below: ESD suppression circuit: Common type of circuit found in the Analog/Digital types of Sensors are ESD suppression circuit . This is a section of the circuit  This is very critical circuit which will protect the PCB's or the tracks of intern...
