It comes in a 6-pin SOT-23 package, surface mount.
Rated for -40°C to 125°C ambient, which covers industrial enclosures, outdoor telecom cabinets, and under-hood automotive modules. That's a full industrial temperature range, so it can sit next to a hot power supply or a processor without derating concerns.
It is RoHS non-compliant, so verify your assembly line's solder alloy compatibility if you're running lead-free.
The reset timeout is 100ms minimum. The part holds the reset output active for at least that long after the monitored voltage returns above the threshold.
No — the voltage threshold is 4.63V, which is designed for monitoring a 5V rail, not a 3.3V rail. For a 3.3V system you would need a supervisor with a lower threshold, typically around 3.0V or 2.9V.
