ABSTRACT:
A circuit is provided for detecting a low power condition which is undesirable and effectively turns off a computer system to prevent incorrect operation thereof. The circuit does not turn on the computer system until the correct power condition is achieved. The circuit is also sensitive to the power condition to establish the time duration permissible for causing the computer system to be turned off.
