8.3.4 Input ORing – Typical Connection
Figure 10 shows how redundant buses may be ORed to a common point to achieve higher reliability. It is possible to have both MOSFETs ON at once if the bus voltages are matched, or the combination of tolerance and regulation causes both TPS2412/13 circuits to see a forward voltage. The ORing MOSFET disconnects the lower-voltage bus, protecting the remaining bus from potential overload by a fault.
