LT2940  
Power and Current Monitor  
FEATURES  
DESCRIPTION  
The LT®2940 measures a high side current and a differ-  
ential 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.

Inverting and Noninverting Open-Collector  
An integrated comparator with inverting and noninvert-  
ing open-collector outputs makes the LT2940 a complete  
power level monitor. In addition, an output current pro-  
portional to the sensed high side current allows current  
monitoring. The current mode outputs make scaling,  
filtering and time integration as simple as selecting ex-  
ternal resistors and/or capacitors.
