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

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

℃.
