Abstract
A slew rate control system for a circuit includes a temperature sensitive device generates a temperature signal. A temperature dependent current source generates a first current source signal. A slew rate controller activates in response to the temperature signal when the temperature exceeds a first threshold. The slew rate controller then generates a slew rate control signal by adjusting slew rate as a function of the temperature signal. The slew rate controller then activates the temperature dependent current source in response to the slew rate control signal.
