Abstract: A positive overshoot detection circuit comprises a transistor coupled to a current mirror, a reference current source coupled to the current mirror, and a comparator coupled to the reference current source and the current mirror. The comparator output indicates whether the current mirror's current is greater than the reference current source's current. A control input and a current terminal of the transistor are coupled to a clamping circuit. A negative overshoot detection circuit comprises a biasing sub-circuit coupled to a transistor, a resistor coupled to the transistor, and a comparator coupled to the transistor and the resistor. The comparator output indicates whether the transistor is in an on or off state. The biasing sub-circuit is coupled to a clamping circuit. In some implementations, the comparator outputs from the positive and negative overshoot detection circuits are provided to a driver circuit, which modifies its operation.
