A semiconductor integrated power device including: an output transistor configured to drive an external load element; a temperature detection circuit configured to: output a first detection signal in reference to a temperature difference between a temperature of the output transistor and an ambient temperature; and output a second detection signal in reference to a temperature difference between a temperature of the output transistor and a first reference temperature; and a current limiter circuit configured to limit a current flowing through the output transistor according to the first detection signal and the second detection signal. The temperature detection circuit activates and inactivates the first detection signal or the second detection signal based on an output of a first hysteresis circuit.
