    µP Supervisory Circuit General Description Features The MIC705, MIC706, MIC707, and 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. Debounced manual reset input is TTL/CMOS
    compatible Reset pulse width: 200ms Watchdog timer: 1.6s (MIC705/706) 4.65V or 4.40V precision voltage monitor Early power-fail warning or low-battery detect 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 and 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. Applications Automotive systems
    Intelligent systems
