HIGH VOLTAGE DETECTION CIRCUIT FOR SEMICONDUCTOR DEVICE

摘要

PURPOSE: A high voltage detection circuit for semiconductor device is provided to minimize the power consumption within a range of a rated supply voltage. CONSTITUTION: A high voltage detection circuit includes a reference voltage generation portion(40) and a high voltage detection portion(50). The reference voltage generation portion generates a reference voltage having a voltage level more than the voltage level of a rated supply voltage of a chip. The high voltage detection portion receives the reference voltage and the supply voltage and outputs an output signal for indicating a high supply voltage when the supply voltage is the high supply voltage having the voltage level more than the voltage level of the reference voltage.
