app note: A simple current-sense technique eliminating a sense resistor

in app notes by DP | 0 comments

An old but interesting app note(PDF) from Microsemi on resistorless current-sensing technique. This application note introduces a simple current-sense technique that eliminates that sense resistor, resulting in system-cost reduction, PCB space saving, and power efficiency improvement. Furthermore, the new current … Read more
