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

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

The SGM708 is available in Green SOIC-8 package. It

operates over an ambient temperature range of -40

℃

to +85

℃.
