Maxim Integrated Product Overview: MAX810LEUR-T

The MAX810LEUR-T is a microprocessor (µP) supervisory circuit designed by Maxim Integrated to monitor power supplies in digital systems. It provides a significant level of system reliability and accuracy required in critical applications. This device is particularly useful in managing system resets by monitoring the system voltage and generating a reset signal whenever necessary.

The MAX810LEUR-T operates by monitoring the VCC for an undervoltage condition. When the VCC falls below the minimum VCC sense level, the reset output is asserted (active low). The reset output remains asserted for a period after VCC has risen above the reset threshold, ensuring the system has sufficient time to stabilize before the processor starts working. This period is known as the reset timeout period.

Key features of the MAX810LEUR-T include:

• Voltage Monitoring: Precision monitoring of 3V, 3.3V, and 5V supply voltages.
• Reset Timeout: 140ms minimum reset timeout period that guarantees the system has time to recover after a power disturbance.
• Low Power Consumption: The device consumes minimal power, making it ideal for power-sensitive applications.
• Temperature Range: The operating temperature range of the MAX810LEUR-T is from -40°C to +85°C, accommodating a wide range of environmental conditions.
• Small Form Factor: The device comes in a compact SOT-23 package, which is advantageous for space-constrained applications.

Applications for the MAX810LEUR-T are diverse, given its ability to provide reliable system monitoring. It is commonly used in portable/battery-powered equipment, computers, controllers, intelligent instruments, and critical µP and µC power monitoring. Its robustness and precision make it an essential component for maintaining system integrity and preventing data loss or corruption due to power anomalies.

Maxim Integrated's commitment to quality ensures that the MAX810LEUR-T meets the stringent requirements of modern digital systems. By integrating this supervisory circuit into your design, you can enhance the operational stability and reliability of your electronic devices.
