LT2940 Power and Current Monitor - Video Product Brief

Kevin B. Scott - Senior Strategic Marketing Engineer Feb 11th 2010

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.
