Current Sensing For Server Power Monitoring: MOSFET Or Shunt?

Jul 1, 2011 12:00 PM Steele, Jerry, National Semiconductor - Strategic Applications Engineer

Power monitoring systems require current sensing and are typically adjacent to, associated with, or integrated with hot swap controllers in server systems. Many designers have expressed a desire to utilize MOSFET current sensing based on the premise that it is lossless, and eliminating a perceived large loss in shunts....
