Abstract
A driving circuit is provided for providing first and second control signals to respective control electrode of first and second power semiconductor elements coupled in parallel. A range of a safe operation area (SOA) of the first power semiconductor element is larger than that of the second power semiconductor element. The driving circuit compares a voltage level of the second control signal with a first reference voltage or compares a drain-source voltage of the first power semiconductor element with a second reference voltage, and further generates a first voltage according to the comparison result. The first and second reference voltages are related to a temperature of the first and second power semiconductor elements. The driving circuit generates a logic signal according to the first voltage and further generates the first or second control signal according to the logic signal.
