Add To BomTPS259472ARPWR General Description
The TPS259472ARPWR is a member of the TPS25947xx family of eFuses. It is a highly integrated circuit protection and power management solution in a small package. The device provides multiple protection modes using very few external components and is a robust defense against overloads, short-circuits, voltage surges, reverse polarity, and excessive inrush current. With integrated back-to-back FETs, reverse current flow from output to input is blocked at all times, making the device well suited for power MUX/ORing applications as well as systems that need load side energy hold up storage in case the input power supply fails. The device uses a linear ORing based scheme to ensure almost zero DC reverse current and emulates ideal diode behavior with minimum forward voltage drop and power dissipation. Loads are protected from input overvoltage conditions either by clamping the output to a safe fixed maximum voltage (pin selectable) or by cutting off the output if the input exceeds an adjustable overvoltage threshold. The device responds to output overload by actively limiting the current or breaking the circuit. The output current limit threshold as well as the transient overcurrent blanking timer are user adjustable. The current limit control pin also functions as an analog load current monitor. The device is available in a 2-mm x 2-mm, 10-pin HotRod QFN package for improved thermal performance and reduced system footprint.
