Abstract
A driver includes a power supply circuit having first to n-th boost circuits, a circuit that operates based on power supplied from the power supply circuit, and an abnormality detection circuit. The abnormality detection circuit detects an abnormality of an i-th boosted voltage that is generated based on a boost operation of an i-th boost circuit. If an abnormality of the i-th boosted voltage is detected, a j-th boost circuit performs a low-capacity boost operation with a lower current-supply capacity than an ordinary boost operation or stops the boost operation.
