1. A conventional circuit uses a diode after the comparator to rectify the output onto C3. The circuit uses an LT1716 comparator. R2/R3 set up a 10-mV threshold to keep the output normally high, and ...
ORing diodes are a necessary evil of high-reliability systems. They're used to isolate redundant power sources so a failure of one source won't bring down the entire system. Several inherent problems ...
