| description | The invention discloses a power supply clamping circuit. The power supply clamping circuit is coupled to an internal circuit of an integrated circuit through a power line and a ground line, and comprises a switch, a first resistor, a capacitor, an inverter and a voltage detection circuit. The switch is coupled between the power line and the ground line. The first resistor is coupled between the power line and the first node. The capacitor is coupled between the first node and a ground wire. The input end of the inverter is coupled to the first node, and the output end of the inverter is coupled to the control end of the switch. The voltage detection circuit is used for detecting the online voltage of the power supply. In response to detecting that the on-line voltage of the power supply exceeds a threshold value, the voltage detection circuit electrically connects the first node to the ground wire, so that a low-potential signal from the ground wire is input into the input end of the phase inverter from the f |
