    SGM708

    Low-Cost, Microprocessor Supervisory Circuit
     
    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. It operates over an ambient temperature range of -40 to +85.
