摘要： There are provided upper and lower switching elements 1U to 1W and 2U to 2W for energizing motor drive windings 4U to 4W, a control circuit 20 that starts outputting a control signal for energization based on an energization instruction, pre-drive circuits 8U to 8W and 9U to 9W for controlling ON/OFF of the upper and lower switching elements based on the control signal, and short circuit detection circuits 10U to 10W for detecting short circuits in a node 14 between the upper and lower switching elements to higher-potential and lower-potential power sources based on the control signal and a voltage of the node. The short circuit detection circuits are controlled to detect a short circuit in the node to the lower-potential power source with all the upper switching elements turned ON and all the lower switching elements turned OFF and to detect a short circuit in the node to the higher-potential power source with all the upper switching elements turned OFF and all the lower switching elements turned ON, in a state where the motor drive windings are not energized. It is possible to prevent a situation in which a short circuit cannot be detected depending on a resistance component of a drive target.

摘要： A semiconductor device includes a phase compensation circuit 6 using a MOS capacitor with a structure in which an insulating film is disposed between a gate electrode formed on a semiconductor substrate and a diffusion layer. The phase compensation circuit includes first and second MOS capacitors 14, 15. A gate electrode terminal of the first MOS capacitor is connected equivalently to a diffusion layer terminal of the second MOS capacitor that is a terminal opposite to the gate electrode terminal. A potential difference generating element 16 that generates a potential difference by allowing a current to flow therethrough is connected between a diffusion layer terminal of the first MOS capacitor and a gate electrode terminal of the second MOS capacitor. When the MOS capacitors having the voltage dependence are used, e.g., as a phase compensation circuit element of an operational amplifier, the MOS capacitance is not reduced, no matter the range of the input or output voltage of the operational amplifier, so that the phase margin will not reduced.
