Abstract
A temperature-compensating clock frequency monitor circuit may be provided to detect a clock pulse frequency in an electronic device that may cause erratic or dangerous operation of the device, as a function of an operating temperature of the device. The temperature-compensating clock frequency monitor circuit include a temperature sensor configured to measure a temperature associated with an electronic device, a clock having an operating frequency, and a frequency monitoring system. The frequency monitoring system may be configured to determine the operating frequency of the clock, and based at least on (a) the operating frequency of the clock and (b) the measured temperature associated with the electronic device, generate a corrective action signal to initiate a corrective action associated with the electronic device or a related device. The temperature sensor, clock, and frequency monitoring system may, for example, be provided on a microcontroller.
