Abstract
A method for protecting a system circuit from electrostatic discharge, switching the system operation state into an idle mode when displacement of a mechanical component takes place to set the state of the system chip to a non-operating state, and preventing the system chip from being damaged by static electric charge impact caused by external electrostatic discharge.
Claims8
A method for protecting a system circuit from electrostatic discharge, comprising the following steps:
- detecting whether a system is in an abnormal operating state;
- sending out a first signal;
- switching the system to an idle mode according to the first signal;
- detecting whether the system is in a state for normal operation;
- sending out a second signal;
- and
- switching the system out of the idle mode according to the second signal.
4 more elements
An electrical system comprising:
- a casing;
- a detector module, disposed on the casing, for detecting whether the electrical system is in an abnormal operation state, wherein the detector module outputs a first signal when the detector module detects that the electrical system is in the abnormal operation state, and outputs a second signal when the detector module detects that the electrical system is in the state for normal operation;
- and
- a microprocessor, electrically connected to the detector module, for controlling the electrical system and for receiving the first signal and the second signal, wherein when the first signal is received, the microprocessor switches the electrical system into an idle mode, and when the second signal is received, the microprocessor switches the electrical system out of the idle mode.
