Abstract

Disclosed is a circuit arrangement for protecting a final power output element comprising semiconductor switches, especially in control devices for motor vehicles. The semiconductor switches (2-5) are provided with temperature sensors (11-14) which cooperate with a control circuit (7-9) such that control pulses stop being supplied to the semiconductor switches when a predefined temperature of at least one of the semiconductor switches (2-5) is exceeded. At least one current-limiting resistor (23-25) is arranged in a load circuit formed by the semiconductor switches.
