    MIC803
    3-Pin Microprocessor Supervisor Circuit
    with Open-Drain Reset Output General Description Features The MIC803 is a single-voltage supervisor with open-drain
    reset output that provides accurate power supply
    monitoring and reset generation in microprocessor-based
    systems. The function of the device is to assert a reset
    signal if the power supply voltage drops below the reset
    threshold voltage, and retain this reset for the reset
    timeout period once the power supply increases above the
    reset threshold voltage. The MIC803 consumes only 4.5ВµA of supply current and
    offers three reset delay periods of 20ms, 140ms, and
    1120ms (minimum). It features factory-programmed reset
    threshold levels from 2.63V to 4.63V to accommodate
    3.0V, 3.3V, and 5.0V power supplies. It is available in the
    compact 3-pin SC-70 and SOT-23 packages.
