The MAX809SEUR from Maxim Integrated is a compact, highly efficient microprocessor (μP) supervisory circuit designed to monitor power supplies in μP and digital systems. It provides a significant function in these systems by asserting a reset signal whenever the VCC supply voltage declines below a preset threshold, ensuring the proper operation of the μP when power is applied.

Key Features

• Precision Monitoring: This device features a precision voltage monitor that keeps a watchful eye on the system's power supply, ensuring that the connected microprocessor is reset with accuracy whenever necessary.
• Low Power Consumption: With its low power consumption, the MAX809SEUR is an ideal choice for portable and battery-operated devices, helping to extend the overall battery life of the system.
• Manual Reset Input: It includes a manual reset input that allows the reset to be triggered with an external switch or logic signal, providing additional control to the system operator or other circuitry.
• Reset Timeout: After the VCC has risen above the reset threshold, the MAX809SEUR maintains the reset output in the active state for a preset timeout period, ensuring the μP has adequate time to initialize.
• Compact SOT Package: The device comes in a small SOT-23 package, making it suitable for space-constrained applications without compromising performance.

Applications

The MAX809SEUR is versatile and can be used in a variety of applications that require reliable system monitoring and reset capabilities. These include:

• Computers and Servers
