Product details

What this supervisor IC does on your board

The output is open-drain, active low, pulled up to the logic voltage with an external resistor. Rated for -40°C to 125°C, this IC handles industrial and automotive under-hood environments — engine control modules, transmission controllers, or any ECU that sees under-hood heat. The SOT-23-8 package is small enough for space-constrained designs but still hand-solderable for bench work.

Active production — no obsolescence worry

The MAX6753KA29 is listed as Active in production. No last-time-buy, no end-of-life notice on the horizon. For a BOM freeze or a long-life design, this part carries no lifecycle risk. RoHS status is noted as non-compliant, so verify your assembly house's exemption policy if you need full RoHS compliance — this may be a lead-bearing finish for high-reliability applications.

Sourcing and fit for your BOM

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.

Frequently asked questions

What is the exact reset threshold voltage of MAX6753KA29?

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.

Is MAX6753KA29 a pin-to-pin replacement for MAX6753KA27?

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.

What is the reset timeout duration of MAX6753KA29?

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.

Is MAX6753KA29 available in tape and reel packaging?

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.

Can MAX6753KA29 be used for 3.3V systems?

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.
