    Micro-Power Low Voltage Supervisor General Description Features The MIC2776 is a power supply supervisor which provides
    under-voltage monitoring and power-on reset generation in a
    compact 5-pin SOT package. Features include an adjustable
    under-voltage detector, a delay-generator, a manual reset
    input, and a choice of active-high, active-low, or open-drain
    active-low reset output. The user-adjustable monitoring input
    is compared against a 300mV reference. This low reference
    voltage allows monitoring voltages lower than those supported
    by previous supervisor ICs.
    The reset output is asserted for no less than 140ms at poweron and any time the input voltage drops below the reference
    voltage. It remains asserted for the timeout period after the
    input voltage subsequently rises back above the threshold
    boundary. A reset can be generated at any time by asserting
    the manual reset input, /MR. The reset output will remain active at least 140ms after the release of /MR. The /MR input
    can also be used to daisy-chain the MIC2776 onto existing
    power monitoring circuitry or other supervisors. Hysteresis
    is included to prevent chattering due to noise. Typical supply
    current is a low 3.0ВµA. User-adjustable input can monitor supplies as low as
    0.3V В±1.5% threshold accuracy Separate VDD input Generates power-on reset pulse (140ms min.) Manual reset input Choice of active-high, active-low or open-drain activelow reset output Inputs can be pulled above VDD (7V abs. max.) Open-drain output can be pulled above VDD (7V abs.
