SGM708 Low-Cost, Microprocessor Supervisory Circuit GENERAL DESCRIPTION The SGM708 microprocessor supervisory circuit reduces the complexity and number of components required to monitor power supply and monitor microprocessor activity. It significantly improves system reliability and accuracy compared to separate ICs or discrete components. The SGM708 provides power supply monitoring circuitry that generates a reset output during power-up, power-down and brownout conditions. The reset output remains operational with VCC as low as 1V. In addition, there is a 1.25V threshold detector for power-fail warning, low-battery detection, or monitoring an additional power supply. An active-low manual-reset input ( MR ) is also included. The SGM708 is available in Green SOIC-8 package.
