Product details

Push-pull output, no external pull-up needed

The output is push-pull, totem pole — active low. That means it drives the reset line low when triggered and high when released, with no external pull-up resistor required. It's a direct drive to the reset input of most microcontrollers and logic families.

Package and footprint for hand-soldering

Housed in a SOT-23-3 package (also known as TO-236-3 or SC-59), this is a three-pin surface-mount part. The SOT-23 is one of the most hand-solderable SMD packages — a fine-tipped iron and some flux, and you're set. No need for a hot-air station or reflow oven, which makes it a practical choice for prototypes and small-batch builds.

Industrial temperature range covers most environments

Not rated for the full military range, but the industrial grade handles the vast majority of commercial and light-industrial applications.

It is ROHS3 compliant. For current availability and pricing, submit an RFQ — we source through independent distribution and confirm pricing and stock at quote time.

Frequently asked questions

Does MAX6346UR44+T have push-pull or open-drain output?

No external pull-up resistor is needed.

What is the reset timeout of MAX6346UR44+T?

The reset timeout is a minimum of 100ms. After the monitored voltage rises above the threshold, the reset output stays low for at least this duration to allow the system to stabilize.

What is the closest pin-compatible alternative to MAX6346UR44+T in this component family?

Within the same MAX6346 family, parts differ by voltage threshold. For example, the MAX6346UR29+T has a 2.93V threshold, while the MAX6346UR44+T is set at 4.38V. All share the same SOT-23-3 footprint and pinout, so swapping thresholds is a straight drop-in if the monitored rail voltage changes.
