Patent 7126391 was granted and assigned to Cypress Semiconductor Corporation on October, 2006 by the United States Patent and Trademark Office.
In one embodiment, a power on reset circuit includes a main circuit and a translation circuit. The main circuit may be configured to receive an external signal and to generate an input signal that is indicative of a state of the external signal. The translation circuit may be configured to receive the input signal and provide a power on reset signal indicative of a brownout condition of the external signal. The external signal may be a relatively high voltage signal compared to the power on reset signal.
