TPS259474ARPWR General Description

The TPS25947xx family of eFuses stands out as a highly integrated circuit protection and power management solution in a compact form factor. These devices offer multiple protection modes with minimal external components, effectively guarding against overloads, short-circuits, voltage surges, reverse polarity, and excessive inrush current. The integration of back-to-back FETs ensures constant blocking of reverse current flow from output to input, making the eFuses well-suited for power MUX/ORing applications and systems that require load side energy hold up storage in the event of input power supply failure. Additionally, the devices employ a linear ORing based scheme to minimize DC reverse current and replicate ideal diode behavior with low forward voltage drop and power dissipation. With an array of advanced features, the TPS25947xx family of eFuses is a versatile and reliable solution for diverse applications, ranging from automotive electronics to industrial machinery
