    MIC811/812
    Microprocessor Reset Circuits General Description Features The MIC811 and MIC812 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 1V 5ОјA typical supply current 140ms minimum reset pulse width available Manual reset input Available in 4-pin SOT-143 package The function of this device is to assert a reset if either the
    power supply drops below a designated reset threshold
    level or /MR is forced low. Several different reset threshold
    levels are available to accommodate 3V, 3.3V or 5V
    powered systems.
    The MIC811 has an active low /RESET output, while the
    MIC812 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 designed reset
    threshold level. Having a push-pull output stage, the
    MIC811/812 does not require a pull-up resistor at the
    output. The MIC811/812 comes in a 4-pin SOT-143
    package. Applications Portable equipment
    Intelligent instruments
    Critical microprocessor power monitoring
    Printers/computers
    Controllers If a microprocessor voltage supervisor with an open-drain
    output stage is needed, see MIC6315.
