The TPS259461LRPWR is a high-side electronic fuse from Texas Instruments that protects downstream circuitry from overcurrent and overvoltage events. Its input range spans 2.7V to 23V, covering common 3.3V, 5V, 12V, and 24V rails — one BOM line for multi-voltage designs. Continuous output current is rated at 5.5A, enough for most point-of-load applications from USB hubs to industrial actuators.
