Abstract
A driver circuit having an overcurrent protection function is configured to: output, when a current value of an output transistor exceeds a threshold value, a shut-off signal for turning OFF the output transistor; output an interval signal for turning ON the output transistor after a predetermined time interval has elapsed from a timing at which the shut-off signal is output when the control signal is in a control state for turning ON the output transistor; and turn OFF the output transistor when any one of the interval signal and the shut-off signal is in a state for turning OFF the output transistor.
