1、 SGM706 Low-Cost, Microprocessor Supervisory Circuit 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 re

2、mains operational with VCCas 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. It operates over an ambient temperature range of -40 to +85. FEATURES z Prec

6、led with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications. SGMICRO reserves the right to make any change in circuit design, specification or other related things if necessary without notice at
