DECEMBER2017–REV. B

GENERAL DESCRIPTION

The SGM706 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 SGM706 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.

Independent watchdog monitoring circuitry is also

provided. This is activated if the watchdog input has not

been toggled within 1.6 seconds.

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 SGM706 is available in Green SOIC-8 package.

The SGM706-S is available in both Green SOIC-8 and

MSOP-8 packages. They operate over an ambient

temperature range of -40

℃ to +85℃.
