www.DataSheet4U.com MIC705/6/7/8 µP Supervisory Circuits MIC705/6/7/8 µP Supervisory Circuits Description The MIC705/MIC706/MIC707/MIC708 are inexpensive microprocessor supervisory circuits that monitor power supplies in microprocessor based systems. The circuit functions include a watchdog timer, microprocessor reset, power failure warning and a debounced manual reset input. The MIC705 and MIC706 offer a watchdog timer function while the MIC707 and MIC708 have an active high reset output in addition to the active low reset output. Supply voltage monitor levels of 4.65V and 4.4V are available. The MIC705/MIC707 have a nominal reset threshold level of 4.65V while the MIC706 and MIC708 have a 4.4V nominal reset threshold level. When the supply voltage drops below the respective reset threshold level, RESET is asserted.
