Active production — SC-70-4 supervisor with 1.665V threshold
The MAX6835IXSD0+T: The 70µs typical reset timeout provides enough hold time for most processor power-on sequences and brief brownout events without nuisance resets.
The 4-pin footprint is compact enough for space-constrained designs but still hand-solderable with a fine-tip iron — no hot-air required for rework. Surface-mount mounting and strip packaging suit automated pick-and-place assembly. The 1.665V threshold matches low-voltage core rails common in 1.8V and 1.5V logic families — a 1.8V rail dipping below 1.665V triggers the reset before the processor enters an undefined state.
Compliance and sourcing
The MAX6835IXSD0+T is ROHS3 compliant, which covers the current EU RoHS exemption list.
