Description

technical field [0001] The invention relates to the field of electrostatic discharge circuits, in particular to an electrostatic discharge circuit with high reliability. Background technique [0002] Static electricity is a kind of charge in a static state. Static electricity is formed when charges accumulate on an object or surface, and static electricity is also divided into positive static electricity and negative static electricity. Static electricity is most likely to occur during the dry and windy winter months. When discharging static electricity, in the field of electronic equipment, since there are integrated circuits inside the electronic equipment, there are too many electronic components in the integrated circuits. The electrostatic voltage of a person on a carpet sofa can be as high as more than 10,000 volts, which is extremely destructive to electronic equipment. Especially for handheld devices, electronic devices that are often in contact with people. Elect...
