Abstract
An overcurrent protection circuit includes a first mirror transistor configured to be driven by a first drive signal, common to a first output transistor, so as to pass a first mirror current, a second mirror transistor configured to be driven by a second drive signal so as to pass a second mirror current, a resistor configured to be connected between a control terminal of each of the first output transistor and the first mirror transistor and a control terminal of the second mirror transistor, and a current restriction unit configured to control the first drive signal such that a sense current, which is a total of the first mirror current and the second mirror current, is restricted to values equal to or less than a predetermined upper limit value.
