Active production — no last-time-buy pressure
The TPS25200QDRVTQ1: This is a current-production part from Texas Instruments, qualified under the Automotive, AEC-Q100 series.
AEC-Q100 qualification and the 125°C junction limit
That covers the under-hood and cabin-environment thermal profiles — an engine-control module or transmission controller that sees 105°C ambient still has margin to the 125°C junction ceiling. The AEC-Q100 stamp means the part passed the full suite of automotive stress tests: high-temperature operating life (HTOL), temperature cycling, ESD, and latch-up.
Input rail and output current — sizing the eFuse
The output current limit is 2.4A — this is the nominal trip threshold, not an absolute maximum. The ±6.3% accuracy on the current limit means the actual trip point falls between 2.25A and 2.55A across temperature and process. That accuracy band is tighter than a polyfuse or a PTC, which can vary 20-30% over temperature. If the downstream load is a sensitive automotive ECU that cannot survive a sustained 3A fault, this eFuse holds the threshold within a predictable window.
The TPS25200QDRVTQ1 comes in a 6-WDFN exposed-pad package, also described as a 6-WSON with a 2x2 mm body. The package is available in Tape & Reel for production pick-and-place, or Cut Tape for prototype builds. The 6-pin footprint is compact enough for space-constrained automotive modules like headlamp controllers or body-control nodes.
