    Abstract: A system includes a voltage surge protection circuit that receives a source voltage from a source. The voltage surge protection circuit includes a reference circuit to generate a reference voltage based on the source voltage when the source voltage exceeds a clamping voltage and a feedback control circuit to receive the reference voltage and clamp an output voltage to the clamping voltage when the voltage from the source exceeds the clamping voltage. A dynamic resistance of the feedback control circuit is substantially zero.

    Abstract: A bidirectional level shifter circuit includes first and second driver circuits, first and second comparators, and a control circuit. The first driver circuit includes a first driver output and a first enable input. The second driver circuit includes a second driver output and a second enable input. The first comparator includes a first comparator output, a first reference input, and a first comparator input that is coupled to the second driver output. The second comparator includes a second comparator output, a second reference input, and a second comparator input is coupled to the first driver output. The control circuit includes a first control input coupled to the first comparator output, a second control input coupled to the second comparator output, a first control output coupled to the first enable input, and a second control output coupled to the second enable input.
