    Microprocessor Reset Circuits General Description Features The MIC809 and MIC810 are inexpensive microprocessor
    supervisory circuits that monitor power supplies in
    microprocessor-based systems. Precision voltage monitor for 3V, 3.3V, or 5V power
    supplies /RESET remains valid with VCC as low as 1.4V for
    SOT-23 packaged part /RESET remains valid with VCC as low as 1V for
    SC70-packaged part Typically less than 15ОјA supply current for SOT-23
    packaged part 5ВµA (typical) supply current for SC70-packaged part 140ms (minimum) reset pulse widths available Available in 3-pin SOT-23 and SC-70 package The function of these devices is to assert a reset if the
    power supply drops below a designated reset threshold
    level. Several different reset threshold levels are available
    to accommodate 3V, 3.3V or 5V powered systems.
    The MIC809 has an active-low /RESET output, while the
    MIC810 offers an active-high RESET output. The reset
    output is guaranteed to remain asserted for a minimum of
    140ms after VCC has risen above the designated reset
    threshold level. Having a push-pull output stage, the
    MIC809/810 does not require a pull-up resistor at the
    output. The MIC809/810 comes in a 3-pin SOT-23 and
    SC-70 package.
    The MIC809 is also available with a shorter reset timeout
    (30ms, minimum).
