Abstract
A semiconductor integrated circuit device includes the following. An output transistor is connected between a voltage input terminal and a voltage output terminal. A control circuit controls an on state or an off state of the output transistor. An overcurrent detection circuit is capable of detecting a current that is a predetermined value or more flowing in the output transistor. A retry circuit generates and outputs a signal to intermittently switch the output transistor to the off state according to the overcurrent detection circuit detecting an overcurrent state. An external terminal outputs an error flag signal showing an abnormality. The control circuit repeats control to temporarily turn off the output transistor. After the overcurrent detection circuit detects the overcurrent state, the retry circuit is configured so that the error flag signal continuously shows an abnormality while the control circuit repeats control to temporarily turn off the output transistor.
