Abstract:
A semiconductor device and an electronic apparatus incorporating the semiconductor device are disclosed. The semiconductor device includesa power circuit that further includes a power transistor for providing current to a load (load current), a temperature detector for detecting the temperature of the power transistor, and a current detector for detecting the load current. If the detected temperature of the power transistor reaches a first predetermined temperature, and if the detected load current exceeds a first predetermined load current, a signal is output through an external terminal of the semiconductor device.
