Supervisor IC in SOT-23-6 — threshold and timeout for the BOM
The MAX6343ZUT+T: The reset timeout is 100ms minimum, which gives the monitored rail time to stabilize after power-up before the processor or logic starts executing code — long enough to cover most power-supply ramp profiles without external timing components. Housed in a SOT-23-6 package (supplier device package SOT-6), it takes up minimal board area and suits compact, single-rail designs where board space is the limiting factor.
Temperature grade and sourcing reality
Lifecycle status is active per Analog Devices, and the part carries ROHS3 compliance — no last-time-buy or obsolescence pressure on this order code.
Open-drain output and reset behaviour
Because the output is open drain, multiple supervisor outputs can be wire-ORed onto a single reset line — useful in multi-rail systems where any rail fault must trigger a system reset.
