The ±6 % current-limit accuracy means you budget about 150 mA of guard band above your nominal load to avoid nuisance trips at the high end of the tolerance band. For a 2 A steady-state design, set the limit at roughly 2.3 A; the ±6 % window keeps the actual trip point between about 2.16 A and 2.44 A.
Industrial temperature range — where this part lives
Without that pad soldered, the package's own thermal resistance will push the die past the limit well before 2.5 A.
For a new-design BOM, this means zero obsolescence risk on the horizon; for a production line already using it, the supply channel is stable and dual-sourcing is not yet urgent.
