The DS1814AR-10+T&R is listed as Active in production with ROHS3 compliance.
No — the 4.375V threshold is designed for 5V systems. For 3.3V rails, select a supervisor with a threshold near 2.93V or 3.08V.
Within the MicroMonitor family, the DS1813 series offers similar functionality with different threshold voltages. Check the specific threshold and timeout requirements against the DS1813 datasheet for pin-compatible options.
The listed type is Simple Reset/Power-On Reset — a basic supervisor that asserts reset on power-up and brown-out conditions.
The reset output is Active Low — the reset signal goes low when triggered.
