Circuit for detecting a supply voltage drop and for resetting an initialization circuit |
摘要 |
A circuit detecting the drop of a supply voltage applied between a high voltage supply terminal and a low voltage supply terminal for an integrated circuit. A trheshold circuit includes an input terminal connected to the high voltage supply terminal, an output terminal supplying a desired signal and threshold supply terminals. A MOS capacitor is connected between the low voltage supply terminal and an N-channel MOS transistor. The drain and gate of the transistor are connected together and to the high voltage supply terminal. The threshold supply terminals are connected across the capacitor.
