The TPS2663x devices are easy to use, positive 60 V and 6-A eFuse with a 31-mΩ integratedFET. It features a B-FET driver to control an external N-channel FET in the system designs thatrequire protection from input reverse polarity faults and reverse current blocking. The deviceincorporates robust protection features that simplify system designs requiring protection duringsystem tests like IEC61000-4-5 industrial surge tests. The device features an adjustable outputpower limiting (PLIM) functionality that simplifies the system design requiring compliance inaccordance to the standards like IEC61010-1 and UL1310. Additional protection features includeadjustable overcurrent protection, fast short circuit protection, output slew rate control,overvoltage protection and undervoltage lockout.
For system status monitoring and downstream load control, the device provides fault and aprecise current monitor output. PGOOD can be used for enable and disable control of the downstreamDC-DC converters. The MODE pin allows flexibility to configure the device between the twocurrent-limiting fault responses (latch off and auto-retry).
