EXCESS VOLTAGE PROTECTION CIRCUIT, METHOD OF PROTECTING A CIRCUIT FROM EXCESS VOLTAGE, AND SEMICONDUCTOR APPARATUS HAVING THE EXCESS VOLTAGE PROTECTION CIRUIT |
| 摘要 |
<p>In a disclosed excess voltage protection circuit, when the input voltage equal to or higher than a predetermined maximum voltage is detected by an excess voltage detection circuit, a switching element is shut off so as to prevent the input voltage being output from the excess voltage protection circuit. A voltage obtained by dividing the input voltage using resistors is output from the excess voltage protection circuit.</p> |
