More Information
Summary:An output driver in an integrated circuit includes a driver circuit operable by a power supply voltage and coupled to an output pad, and a driver power conditioner configured to generate a fractional pad voltage in response to a voltage on the output pad and to provide the fractional pad voltage to at least one transistor of the driver circuit as a protected supply voltage in response to an absence of the power supply voltage.
