2A current switch with ±6% accuracy — what it buys the BOM
The TPS25221DRVT from Texas Instruments is a current-limiting power switch that delivers up to 2A continuous output across a 2.5V to 5.5V input range. The ±6% current-limit accuracy is the spec that matters for the overcurrent threshold: at a 2A set point, the trip window spans 1.88A to 2.12A, so the downstream load must stay clear of the lower bound to avoid nuisance shutdown.
Temperature range and package — where it fits physically
Surface-mount only; the 6-WDFN Exposed Pad case code matches the 6-WSON supplier package.
No official second source or pin-compatible cross-reference is listed, so dual-sourcing requires a functional equivalent from a different family.
