The reset that catches a 5V rail sag before the MCU glitches
When the supply drops below that level, it asserts an active-low reset output — push-pull, no external pull-up needed.
AEC-Q100 and the 125°C ceiling — where this reset lives
That puts it in the under-hood and engine-bay temperature envelope, where a standard 85°C reset would drift or latch up. The SOT-23-5 package (SC-74A) keeps the footprint small enough for cramped ECU layouts, but the 0.95 mm pitch means a decent soldermask web between pads — no fine-pitch surprises for the PCB layout engineer.
That means TI is not actively developing this variant, and it may move to last-time-buy without a long window. But any new BOM should look at the wider TPS382x family for a pin-compatible replacement with similar threshold and timeout options.
