If your MCU requires a longer power-up delay — say 200ms for a crystal oscillator or a slow-start power module — this part may not hold the reset long enough. In that case you would need a supervisor with a longer timeout or an external RC delay on the reset line.
That means no last-time-buy risk and no forced redesign for obsolescence. It is ROHS3 compliant.
The output is push-pull (totem pole), active low. No external pull-up resistor is required.
Yes. The 2.93V threshold is designed to monitor a 3.3V supply rail. It is not suitable for 5V or 1.8V rails without a voltage divider.
The DS1706SEUA+ is part of the MicroMonitor™ series. A direct pin-compatible equivalent from Maxim Integrated would be another member of the same series with the same package and threshold voltage — confirm the exact order code against your BOM threshold and timeout requirements.
