A power switching circuit provides temperature compensation for an insulated gate power switching device. A timing circuit determines a switch timing signal comprising desired on and off switching times of the switching device. A temperature monitor quantifies a device temperature. A gate drive profile generator generates a switching device drive signal according to the switch timing signal and having a dv/dt phase and a di/dt phase. The drive signal has a profile during the di/dt phase that is adjusted in response to the device temperature, and the drive signal has a profile during the dv/dt phase that is not adjusted in response to the device temperature.
