Abstract
A signal protection circuit, a driving method thereof, and a device. A voltage division circuit divides a voltage of an input signal end and outputs a divided voltage. When the divided voltage is greater than a first threshold voltage and the divided voltage is less than a second threshold voltage, a signal control circuit outputs a first-level switch control signal. In this way, an output control circuit can connect the input signal end with an output signal end in response to the first-level switch control signal. When the divided voltage is less than the first threshold voltage or the divided voltage is greater than the second threshold voltage, the signal control circuit may output a second-level switch control signal. In this way, the output control circuit can connect the input signal end with a ground terminal in response to the second-level switch control signal.
