SEND OFFERS)uP Supervisory CircuitsDESCRIPTIONThe ETC705/ETC706/ETC707/ETC708 are inexpensivemicroprocessor supervisory circuits that monitor powersupplies in microprocessor based systems. The circuitfunctions include a watchdog timer, microprocessorreset, power failure warning and a debounced manualreset input.The ETC705 and ETC706 offer a watchdog timerfunction while the ETC707 and ETC708 have an activehigh reset output in addition to the active low resetoutput.Supply voltage monitor levels of 4.65V and 4.4V areavailable. The ETC705/ETC707 have a nominal resetthreshold level of 4.65V while the ETC706 and ETC708have a 4.4V nominal reset threshold level. When thesupply voltage drops below the respective resetthreshold level, RESET is asserted.FEATURESDebounced Manual Reset Input isTTL/CMOS Compatible· Reset Pulse Width, 200ms· Watchdog Timer, 1.6s (ETC705/ETC706)· 4.4V or
