Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of electrostatic protection, and relates to an electrostatic protection device, in particular to an electronic device with electrostatic protection function. BACKGROUND

[0002] With the continuous development of science and technology, the intelligent degree is higher and higher, so that the application of chips is more and more extensive, and the integration degree is continuously improved. As a result, the electromagnetic compatibility problem is more and more prominent, and the electrostatic protection is an EMC problem that is not easy to solve. There are many reasons for the generation of static electricity, including the following scenarios.

[0003] (1) triboelectricity: when two different materials are in contact and separated by friction, one material will gain electrons and become negatively charged, and the other material will lose electrons and become positively charged due to the transfer of electrons;

[0004] (2) induction electrification: when a charged body approaches a neutral object, due to the action of the electric field, one side of the neutral object will lose electrons and become positively charged, and the other side will gain electrons and become negatively charged;

[0005] (3) contact electrification: when two objects are in contact, electrons can be transferred from one object to another, making one object positively charged and the other object negatively charged.

[0006] For static electricity, protective devices such as capacitors, ESD tubes, resistors, magnetic beads, etc. can be used for protection, but when the environment is severe to a certain extent, static electricity can even directly discharge to the chip and even the chip pin; the chip is easy to be directly damaged, and the above protection cannot play a good role.
