CIRCUIT DEVICE, ELECTRO-OPTICAL DEVICE, AND ELECTRONIC APPARATUS

摘要

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.

主权项

1. A circuit device, comprising:
a power supply circuit having first to n-th boost circuits, “n” being an integer of n≧2; a circuit that operates based on power supplied from the power supply circuit; and an detection circuit, wherein the 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 of the first to n-th boost circuits, “i” being an integer of 1≦i≦n, and if an abnormality of the i-th boosted voltage is detected, a j-th boost circuit of the first to n-th boost circuits performs a low-capacity boost operation with a lower current-supply capacity than an ordinary boost operation or stops the boost operation, “j” being an integer of 1≦j≦n and j≠i.
