TI TPS26631RGER

The TPS2663x devices are easy-to-use positive 60V and 6A electronic fuses that include an integrated 31mΩ FET. The device features a B-FET driver for controlling an external N-channel FET in system designs that require input reverse polarity fault and reverse current blocking protection. The device integrates robust protection features to simplify system designs that require protection during system testing, such as the IEC61000 - 4 - 5 industrial surge test. The device has an adjustable output power limit (PLIM) feature, which simplifies system designs that need to comply with standards such as IEC61010 - 1 and UL1310. Other 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 accurate current monitor outputs. PGOOD can be used to enable and disable downstream DC/DC converter control. The MODE pin can be used to flexibly configure the device between two current limit fault responses (latch and auto-retry).
