LT2940 Power and Current Monitor Features n n n n n n n n n DESCRIPTION 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 parator with inverting and noninverting open-collector outputs makes the LT2940 a plete power level monitor. In addition, an output current proportional to the sensed high side current allows current monitoring. The current mode outputs make...
