Product details

What this watchdog does on the board

The -40°C to 125°C operating temperature range covers industrial enclosures, outdoor telecom cabinets, and under-hood automotive environments where a microcontroller needs a reliable watchdog to recover from code lockups or supply glitches.

100ms reset timeout — what it buys you

The minimum 100ms reset pulse gives the power supply time to stabilize and the microcontroller time to start up cleanly.

Active lifecycle — no LTB pressure

The MAX6323FUT26 carries an Active product status. For a BOM freeze or a new design, this part doesn't carry obsolescence risk today. This variant is RoHS non-compliant.

Frequently asked questions

What is the reset timeout for MAX6323FUT26?

The reset timeout is 100ms minimum. That's the guaranteed pulse width the part holds reset low after the monitored rail returns above the 2.63V threshold.

Is MAX6323FUT26 compatible with a 5V supply?

No. The 2.63V threshold is designed for a 3.3V rail. On a 5V supply the threshold would trip at roughly half the nominal voltage, which is too low to protect 5V logic from a brownout. For a 5V rail, look for a supervisor with a threshold around 4.63V in the same family.
