SEMICONDUCTOR DEVICE AND POWER SOURCE CONTROL METHOD |
| 摘要 |
There is provided a semiconductor device including: a power source section that steps down a power source voltage to generate a step-down voltage, and that stops generation of the step-down voltage when input with a stop signal; a control section that is driven by the step-down voltage generated by the power source section, and that outputs to the power source section a stop signal to stop generation of the step-down voltage; and a power source controller that prohibits input of the stop signal to the power source section until the step-down voltage has become a predetermined value or greater. |
