    Dual Micro-Power Low Voltage Supervisor General Description Features The MIC2777 is a dual power supply supervisor that provides
    under-voltage monitoring, manual reset capability, and poweron reset generation in a compact 5-pin SOT package. Features include two under-voltage detectors, one fixed and one
    adjustable, and both active-high and active-low reset outputs.
    One under-voltage detector compares VDD against a fixed
    threshold. Ten factory-programmed thresholds are available.
    The other under-voltage detector is user-adjustable.
    The reset outputs are asserted for no less than 140ms at
    power-on and any time VDD or the input voltage drops below
    the corresponding reference voltage. They remain asserted
    for the timeout period after the input voltage and VDD subsequently rise back above the threshold boundaries. A reset
    can be generated at any time by pulling down on the adjustable input. Hysteresis is included to prevent chattering due
    to noise. Typical supply current is a low 3.5µA. Monitors two independent power supplies for under-voltage conditions One fixed and one user adjustable input 1.5% theshold accuracy Choice of factory-programmed thresholds User-adjustable input can monitor supplies as low as
