The TPS2663x devices are easy to use, positive 60 V and 6-A eFuse with a 31-mΩ integrated FET. It features a B-FET driver to control an external N-channel FET in the system designs that require protection from input reverse polarity faults and reverse current blocking. The device incorporates robust protection features that simplify system designs requiring protection during system tests like IEC61000-4-5 industrial surge tests. The device features an adjustable output power limiting (PLIM) functionality that simplifies the system design requiring compliance in accordance to the standards like IEC61010-1 and UL1310. Additional protection features include adjustable 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 a precise current monitor output. PGOOD can be used for enable and disable control of the downstream DC-DC converters. The MODE pin allows flexibility to configure the device between the two current-limiting fault responses (latch off and auto-retry).
