Device with overcurrent shutdown and over-temperature shutdown

Device with an overcurrent shutdown and an overtemperature shutdown system, with a power element (9), the power from a power supply (2) to a mounted in a vehicle load (10) and the latter current-carrying interrupts, a current detection device (3) which detects a current flowing in the power element (9), a current / voltage converting means that converts the detected current into a voltage signal, and a temperature detecting means (27), characterized in that the temperature detecting means (27) changes the voltage signal or a current signal in response to the heat generation amount of the power element (9), a temporary storage unit (5) is provided, which maintains a predetermined state in response to an output signal from said current detecting means (3) and from the temperature detecting means (27), a return pulse means (26) is provided which receives and passes on or generated, to enable the latch means (5) back into an initial state of a return pulse, and a current-carrying and power-off control means (7) is provided, which carries out the current-carrying and stopping control of the power element (9) in response to the output signal of the latch means (5).
