Problems solved by technology
[0003] However, once the integrated circuit is affected by ElectroStatic Discharge (ESD), some unstable phenomena will often appear, such as sudden malfunction of the function, or the internal circuit of the integrated circuit collapsed due to the unbearable voltage or current of static electricity. damage
Generally, a transient voltage suppressor (TVS) is installed on the periphery of the integrated circuit to prevent damage caused by electrostatic discharge. Manufacturing cost, and the overall circuit layout is limited due to the additional transient voltage suppressor

The invention discloses an integrated circuit possessing electrostatic discharge protection. The integrated circuit comprises a shell, a circuit pin, an internal circuit and an electrostatic discharge protection unit. The internal circuit possesses at least one of a function connection point, a power supply connection point and a grounding connection point. The electrostatic discharge protection unit comprises a first coupling terminal and a second coupling terminal. The first coupling terminal is connected to the function connection point or the power supply connection point. The second coupling terminal is connected to the function connection point or the grounding connection point which is not connected to the first coupling terminal. The electrostatic discharge protection unit is arranged among the plurality of connection points and is packaged in a single integrated circuit so that the integrated circuit possesses an electrostatic discharge protection capability; and then design and manufacturing cost of an integral circuit is reduced and an integral circuit layout possesses flexibility.
Description
technical field [0001] The invention relates to an integrated circuit, in particular to an integrated circuit with electrostatic discharge protection. Background technique [0002] In the modern age of ever-changing technology, electronic products have become an indispensable part of people's daily life, and the rapid evolution and widespread use of integrated circuits (ICs) is one of the important drivers for the rapid development of electronic products. [0003] However, once the integrated circuit is affected by ElectroStatic Discharge (ESD), some unstable phenomena will often appear, such as sudden malfunction of the function, or the internal circuit of the integrated circuit collapsed due to the unbearable voltage or current of static electricity. damage. Generally, a transient voltage suppressor (TVS) is installed on the periphery of the integrated circuit to prevent damage caused by electrostatic discharge. Manufacturing cost, and the overall circuit layout is limit...
