Abstract

Systems, methods, and circuitries are provided for generating an acceleration current in response to a threshold temperature being reached. In one example, temperature based acceleration current source circuitry includes a first temperature sensitive device, a second temperature sensitive device, differential trigger circuitry, and an acceleration current source. The first temperature sensitive device is configured to generate a first signal that varies responsive to temperature changes at a first rate. The second temperature sensitive device is configured to generate a second signal that varies responsive to temperature changes at a second rate. The differential trigger circuitry is configured to generate a trigger signal based on a difference between the first signal and the second signal. The acceleration current source circuitry is configured to output an acceleration current in response to the trigger signal.
