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. It operates over an ambient temperature range of -40 to +85.
