Temperature protection circuit for e.g. power transistor, has schottky diode connected using electronic circuit, which controls power transistor based on current, which flows in reverse direction through schottky diode

摘要

The circuit has a schottky diode (D), which is thermally coupled with a power transistor (T) to be protected from excess temperature in a better manner, and switched in a reverse direction. The schottky diode is connected using an electronic circuit. The electronic circuit controls the power transistor based on the current, which flows in the reverse direction through the schottky diode. The electronic circuit has a transistor (T1) whose control terminal is connected with the diode.
