Abstract
This disclosure is directed to circuits and techniques for detecting or responding to temperature of a power switch based on paired measurements of current and voltage. A driver circuit for a power switch may be configured to perform a current measurement and a voltage measurement associated with a temperature-dependent circuit element and control the power switch based at least in part on the current measurement and the voltage measurement. In some examples, the current and voltage measurements may be used to determine the temperature of the power switch.
