    DESIGN FEATURES L Dual/Triple Power Supply Monitor for
    Undervoltage and Overvoltage on
    Positive and Negative Supplies
    by Andrew Thomas Introduction
    An accurate power supply monitor
    can signal when a supply overvoltage
    or undervoltage condition threatens
    to cause system failures, allowing
    the system to deal with the situation
    gracefully.
    The LTC2909 is a highly customizable monitoring solution with
    adjustable input thresholds, input
    polarity selection, a multimode reset
    timer, and an open-drain RST output.
    Adjustable input thresholds allow the
    user to set any trip threshold for the
    comparator, subject only to the accuracy limitations of the part, instead
    of having to pick from a factory-set
    limited collection of thresholds.
    Each adjustable input can be
    configured in either polarity, allowing it to monitor negative or positive
    supply voltages for undervoltage or
    overvoltage. Polarity selection is controlled by simple connection of the ...
