Abstract
Aspects relate to a calibration trigger for a current sensor of a computing device. In one example, a current sensor controller is configured to receive a temperature signal representing a measured temperature of a computing device. A comparator is configured to determine if the temperature signal exceeds a temperature threshold. A logic gate is configured to trigger a calibration of a current sensor coupled to the computing device in response to the temperature true signal exceeding the threshold.
