    DESIGN FEATURES Programmable Quad Supervisors
    Offer Unparalleled Flexibility for MultiVoltage Monitoring Applications
    by Bob Jurgilewicz Introduction
    Three new power supply supervisors
    improve system reliability by offering
    more accurate reset thresholds than
    other supervisors on the market. They
    also save design time, production
    costs and board space with easy-touse, flexible interfaces and a low
    external parts count.
    The LTC2900, L TC2901 and
    LTC2902 quad supervisors can simultaneously monitor four supply
    voltages with 1.5% threshold accuracy over temperature. Each part
    offers 16 user-selectable four-voltage
    combinations from the following: 5V,
    3.3V, 3V, 2.5V, 1.8V, 1.5V, +ADJ and
    –ADJ. A simple external resistor
    divider performs single-pin programming, eliminating the need to qualify,
    source and stock different part num-5V
