Problems solved by technology

[0008] However, the software method of confirming the status of the registers at periodic intervals, due to the very short time to generate electrostatic discharge ESD, the software method of detecting electrostatic discharge ESD is limited
That is, since the electrostatic discharge ESD detection cannot be completely formed, the refresh operation cannot be performed normally, so the system malfunction to the electrostatic discharge ESD cannot be prevented

Abstract

This invention relates to an ESD-proof device utilizing an integrated circuit to stabilize the ESD phenomenon, in which, said device is composed of the following parts: an integrated circuit receiving signals input by various clock sources generated in the system and testing the abnormal clock signals of the electric impact caused by the ESD, a voltage transformation part designed for down the abnormal clock signal level tested by the integrated circuit and a CPU for receiving the abnormal clock signals output by the voltage transformation part and controlling the refresh operation containing the clock source of the abnormal clock signals.

Description

technical field [0001] The invention relates to an electrostatic discharge prevention device, in particular to an electrostatic discharge prevention device utilizing an integrating circuit. Background technique [0002] Currently, for the TV system (Television System), with the expansion of digital TV (Digital TV) functions, the complexity of the system or in order to solve the complex problems caused by the significant increase in the functions of digital TV, as a solution to this problem The current countermeasures usually adopt a mixed method of combining hardware (H / W) and software (S / W). [0003] In particular, as the use of integrated circuits (ICs) increases in terms of system complexity, the proportion of ESD (Electro Static Discharge) countermeasure technology using software methods is currently increasing. [0004] As countermeasures against electrostatic discharge ESD, there are currently two methods: one is to use (Zener) Zener diode (Zener Diode), or use hardwa...
