EXCESS VOLTAGE PROTECTION CIRCUIT, METHOD OF PROTECTING A CIRCUIT FROM EXCESS VOLTAGE, AND SEMICONDUCTOR APPARATUS HAVING THE EXCESS VOLTAGE PROTECTION CIRCUIT

摘要

When the input voltage above the maximum voltage is detected by the detection circuit, the switching element is short circuited to prevent the input voltage from outputting from the overvoltage protection circuit. The voltage obtained is output from the over-voltage protection circuit by dividing the input voltage of the resistor.
