제4도는 제3도에 따른 출력파형도.4 is an output waveform diagram according to FIG.

Claims (2)

파워 온 리세트회로에 있어서, 시스템의 파워인 동작 전원전압(VDD)에 따라 동작하는 낸드게이트(NAND1) 및 인버터(I1)를 통해 고전위동작파워온리세트신호와 고전위동작파워온리세트신호(RST)를 발생시키도록 칩내부에 구성한 것을 특징으로 하는 파워 온 리세트회로.In the power-on reset circuit, a high potential operating power on reset signal is provided through a NAND gate NAND1 and an inverter I1 operating according to an operating power supply voltage V DD which is the power of a system. And a power-on reset circuit configured to generate a high potential operating power on reset signal (RST). 제1항에 있어서, 낸드게이트(NAND1)의 출력인 고전위동작파워온리세트신호를 그의 일측입력으로 피드백시킴과 아울러 인버터(I1)의 입력으로 인가하고, 그 인버터(I1)의 출력인 고전위동작파워온리세트신호(RST)를 상기 낸드게이트(NAND1)의 타측입력으로 인가하여 구성한 것을 특징으로 하는 파워 온 리세트회로.The high potential operating power on reset signal according to claim 1, which is an output of the NAND gate. Is fed back to its one input and applied to the input of the inverter I1, and a high potential operating power on reset signal RST, which is the output of the inverter I1, is applied to the other input of the NAND gate NAND1. A power-on reset circuit characterized in that the configuration. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
