SGM706

Features

Product Name: Low-Cost Microprocessor Supervisory Circuit Manual Reset Voltage Detection Circuit

Product model: SGM706

Product 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 operationalwith 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 () is also included.

The SGM706 is available in Green SOIC-8 package. It operates over an ambient temperature range of -40°С to +85°С.
