eFuses (integrated hot swaps)

Industry-leading efficiency and reliability and advanced integration deliver high power density for next-gen systems

parametric-filterView all products
TI eFuses help strengthen system reliability with intelligent, solid-state protection against overcurrent, short-circuit, overvoltage, reverse polarity and inrush events. Designed for precision and speed, our eFuses actively detect faults and isolate the load in real time, automatically restoring normal operation once conditions stabilize. Achieve higher efficiency, reduced component count and enhanced system robustness in a compact, thermally optimized design.
