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.
Yes. The input voltage range is 2.7V to 23V, so 5V is well within the operating window. The 5.5A continuous output provides margin for most 5V loads.
