Introduction to Lin Bus and Special Devices for Electrostatic Surge Protection

1、 Introduction to Lin Bus

A. Definition of Lin Bus

Lin bus is a serial communication bus suitable for communication between automotive electronic control units (ECUs).

B. Characteristics of Lin Bus

The Lin bus adopts a single end drive and differential transmission method, which has the characteristics of high-speed transmission and strong anti-interference performance.

C. Application scope of Lin bus

The Lin bus is mainly used for communication between electronic control units (ECUs) in automobiles, such as engine control units, transmission system control units, body control units, and so on. The emergence of the Lin bus enables data exchange and communication between ECUs of different brands, systems, and functions, thereby improving the overall performance and safety of automobiles.

2、 Problems with Lin Bus

A. Hazards of static surges

Static surges and other factors can damage the performance and stability of the Lin bus.

B. Stability and reliability issues of Lin bus

There are also some problems with the Lin bus in practical applications.

3、 Design of electrostatic surge protection

A. Hardware protection measures

The design of electrostatic surge protection needs to start from both hardware and software aspects. In terms of hardware, measures such as protective circuits can be taken to limit electrostatic surge voltage, such as using protective circuits composed of TVS diodes, inductors, capacitors, etc.

Suggestions for the layout of ESD devices

a) Place the device as close as possible to the input or connector.

b) Minimize the path length between the device and the protected line.

c) Keep parallel signal paths to a minimum.

d) Avoid running protected conductors in parallel with unprotected conductors.

e) Minimize the conductive circuits of all printed circuit boards (PCBs), including power and ground circuits.

f) Minimize the transient return path length to ground.

g) Avoid using shared transient return paths to common ground points.

h) Try to use ground planes, multi-layer printed circuit boards, and ground through holes as much as possible.

B. Software protection measures

In terms of software, error Check digit (CRC) and other technologies can be used to detect errors in data transmission, so as to ensure the reliability of data.

4、 The Importance of Lin Bus in the Field of Automotive Electronics

A. Advantages of Lin Bus

The Lin bus has the characteristics of high-speed transmission and strong anti-interference performance.

B. The Application Prospects of Lin Bus

In the future field of automotive electronics, the Lin bus will still play an important role and play an important role.

Summary

The interface protection of electronic products requires the use of overvoltage protection devices. Many engineers are aware of the need to use protection devices, but due to improper selection or failure to follow the design principles of ESD circuit PCB, the product fails static or EMC testing, wastes manpower and financial resources, and causes product delays or over design, resulting in cost pressure. Leiditech Electronics provides customers with electromagnetic compatibility EMC design services, providing laboratory testing for free. We aim to efficiently and conveniently complete the design for our customers. We hope that more customers can quickly pass EMC’s projects and improve product reliability as much as possible.

Shanghai Leiditech Electronic Electromagnetic Compatibility Laboratory provides free testing and peripheral electrostatic protection reference circuits.
