SLVS727E November 2006 – October 2019 TPS2410 , TPS2411
PRODUCTION DATA.
Figure 11 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 TPS2410 and TPS2411 circuits to see a forward voltage. The ORing MOSFET disconnects the lower-voltage bus, protecting the remaining bus from potential overload by a fault.
