Product details

Temperature grade and where it fits

Rated for -40°C to 125°C ambient, this part covers industrial enclosures, outdoor telecom cabinets, and under-hood automotive modules that see the full temperature swing. The SOT-23-6 package is a standard footprint for supervisor ICs — small enough for space-constrained PCBs but still hand-solderable for rework. Surface-mount only; no through-hole variant exists.

Lifecycle and sourcing note

It is RoHS non-compliant, so if your BOM requires RoHS exemption or you are building for a legacy program that accepts tin-lead solder, this part fits.

Frequently asked questions

Does MAX6323AUT46 include a watchdog timer?

Yes, the device type is Watchdog Circuit. It monitors both the supply voltage and a watchdog input; if the watchdog input is not toggled within the timeout period, the part asserts a reset.

What is the reset output type and polarity?

The reset is active-low, push-pull totem-pole. It drives a logic low when the monitored voltage falls below 4.63V or the watchdog times out, and releases high after the 100ms reset timeout.

What is the closest pin-compatible alternative to MAX6323AUT46?

Within the MAX6323 family, the lead-free suffix variant (MAX6323AUT46+T) is pin-compatible and functionally identical, differing only in RoHS compliance. For a different threshold voltage, the MAX6323 family offers multiple threshold options in the same SOT-23-6 footprint.
