SGM706 Low-Cost, Microprocessor Supervisory Circuit GENERAL DESCRIPTION FEATURES The SGM706 microprocessor supervisory circuit reduces Precision Supply-Voltage Monitor the complexity and number of components required to 4.65V for SGM706-L monitor power-supply and monitor microprocessor 4.40V for SGM706-M activity. It significantly improves system reliability and 4.0V for SGM706-J accuracy compared to separate ICs or discrete 3.08V for SGM706-T components. 2.93V for SGM706-S 2.63V for SGM706-R The SGM706 provides power-supply monitoring circuitry Guaranteed RESET Valid at VCC = 1V that generates a reset output during power-up, 200ms Reset Pulse Width power-down and brownout conditions. The reset output Debounced TTL/CMOS-Compatible remains operational with VCC as low as 1V. Independent Manual-Reset Input watchdog monitoring circuitry is also provided. This is Independent Watchdog Timer (1.6sec) Timeout activated if the watchdog input has not been toggled Voltage Monitor for Power-Fail or Low-Battery Warning within 1.6 seconds. -40℃ to +85℃ Operating Temperature Range Green SOIC-8 Package In addition, there is a 1.25V threshold detector for power-fail warning, low-battery detection, or monitoring an additional power supply.
