The DS1708TESA+: This is a current-production part you can spec into a new design without worrying about a forced respin mid-cycle. ROHS3 compliant — no exemption sunset risk for EU or global BOMs. The part ships in tubes, surface-mount 8-SOIC, standard for pick-and-place.
3.08V threshold — the rail it watches
That places it squarely on a 3.3V supply — the 220mV margin between nominal rail and trip point is enough to ride through minor droops without nuisance resets, but tight enough to catch a sagging regulator before the downstream logic starts seeing undefined states. The reset timeout is 130ms minimum — long enough for the bulk capacitance on the rail to stabilize after power-up, short enough that the system isn't waiting an eternity before the CPU starts fetching code.
Dual-polarity reset — one chip, two interfaces
Both active-high and active-low reset outputs are available, push-pull topology. No open-drain pull-up resistor needed on either pin — the outputs drive rail-to-rail directly. This means the same part can serve a processor that expects a low-true reset and a peripheral that needs a high-true flag, without a logic gate in between. The 8-SOIC package is a 3.90mm-wide body, 0.154" pitch — a standard footprint that routes easily on two-layer boards.
