Key Specifications
The MAX809TEUR+T from Analog Devices is a compact microprocessor (μP) supervisory circuit designed to monitor power supplies in digital systems. It provides a reset signal to the host processor whenever the supply voltage falls below a preset threshold, ensuring reliable operation during power-up, power-down, and brown-out conditions.
The MAX809TEUR+T is optimized for 3.3V logic systems. For other supply voltages, refer to the MAX809 family with different threshold options. Ensure the reset threshold matches your system's minimum operating voltage. The push-pull output simplifies interface design; for open-drain requirements, consider alternative models. Verify the reset timeout period and quiescent current in the official datasheet for your specific application.
