It delivers up to 2A continuous output across a 2.5V to 5.5V input range, covering the common 3.3V and 5V system rails used in USB ports, hot-swap controllers, and general-purpose power multiplexing. The ±6% current-limit accuracy means you can set the trip point closer to the load's maximum draw without triggering false limits, which directly reduces headroom required on the upstream supply. For a 2A design, a ±6% band translates to a worst-case limit between 1.88A and 2.12A — tight enough to protect downstream components without oversizing the input rail. ## Temperature grade and package — design-in checklist","metaTitle":"Texas Instruments TPS25221DBVR Current Switch, 2A, SOT-23-6","metaDescription":"Texas Instruments TPS25221DBVR current switch: 2A output, 2.5V-5.5V input, ±6% accuracy, -40°C to 125°C.
