The output is open-drain, active low, pulled up to the logic voltage with an external resistor. The SOT-23-8 package is small enough for space-constrained designs but still hand-solderable for bench work.
No last-time-buy, no end-of-life notice on the horizon.
For volume production or a one-off repair, this part is actively available. The SOT-23-8 footprint is standard; no surprises on the pick-and-place line.
The reset threshold voltage is 2.925V. This is the voltage at which the device asserts a reset (active low) when the monitored rail drops below this level.
Both parts are in the same MAX6753 family and share the same SOT-23-8 pinout, but they have different reset threshold voltages. The MAX6753KA29 has a 2.925V threshold; the MAX6753KA27 has a different threshold (check its datasheet). They are not drop-in replacements unless the threshold matches your rail requirement.
The reset timeout duration is a minimum of 5.692ms. After the monitored voltage rises above the threshold, the device holds reset low for at least this period before releasing it.
The listing shows the package as Bulk. Tape and reel availability may be offered by the manufacturer or distributor — confirm at quote time for your required reel quantity.
Yes, the 2.925V threshold is appropriate for a 3.3V rail, providing about 11% undervoltage margin. Ensure your processor's minimum operating voltage is below 2.925V so the supervisor releases reset only when the rail is stable.
