| description | An overvoltage detection circuit coupled to an external power supply via a voltage supply line and comprising a transistor comprising first terminal coupled to the voltage supply line, second terminal coupled to the first terminal via a resistor, the second terminal coupled to a parasitic capacitor, the transistor configured to receive an overvoltage spike from the external power supply on the first terminal, and provide an output voltage on third terminal of the transistor to indicate detection of the overvoltage spike when it has a duration less than a time constant based on the resistor and the parasitic capacitor and amplitude that exceeds a threshold voltage of the transistor. The overvoltage detection circuit further comprises a monitor circuit configured to receive the output voltage from the transistor and provide a digital signal providing a notification of the detected overvoltage spike from the external power supply on the voltage supply line. |
