    Inverting and Noninverting Open-Collector
    Comparator Outputs
    Available in 12-Pin DFN (3mm × 3mm) and 12-Lead
    MSOP Packages The LT®2940 measures a high side current and a differential voltage, multiplies them and outputs a current
    proportional to instantaneous power. Bidirectional high
    side currents and bipolar voltage differences are correctly
    handled by the four-quadrant multiplier and push-pull
    output stage, which allows the LT2940 to indicate forward
    and reverse power flow.
    An integrated comparator with inverting and noninverting open-collector outputs makes the LT2940 a complete
    power level monitor. In addition, an output current proportional to the sensed high side current allows current
    monitoring. The current mode outputs make scaling,
    filtering and time integration as simple as selecting external resistors and/or capacitors. APPLICATIONS Board Level Power and Current Monitoring
