The MAX6811LU from Maxim Integrated is a sophisticated microprocessor (μP) supervisory circuit designed to monitor power supplies in μP and digital systems. It provides a high degree of precision and reliability in managing system resets, ensuring that your digital system operates smoothly and efficiently.

This compact device is particularly suitable for battery-powered applications due to its low voltage operation and low power consumption. It operates over a wide voltage range of 1.2V to 5.5V, making it versatile for various low-voltage applications. The MAX6811LU is designed to maintain system integrity by monitoring the power supply voltage and asserting a reset if it detects an out-of-tolerance condition.

Key features of the MAX6811LU include:

• Reset Threshold Options: The device comes with factory-trimmed reset threshold voltages, which can be selected to match the voltage requirements of specific applications.
• Low Power Consumption: With its low quiescent current of only 1µA, the MAX6811LU is optimized for power-sensitive designs, extending battery life in portable devices.
• Manual Reset Input: This feature allows for a manual system reset, providing designers with additional flexibility and control over system behavior.
• Reset Timeout: The MAX6811LU ensures that the system's microprocessor is held in the reset state for a minimum timeout period after the supply voltage becomes valid, ensuring proper system initialization.
• Compact Packaging: Available in a small, space-saving 3-pin SOT23 package, the device is ideal for applications where board space is at a premium.

The MAX6811LU is highly reliable, featuring an immune to short V<sub>CC transients design. It is a perfect choice for portable computers, controllers, intelligent instruments, critical μP power monitoring, and other applications that require a high level of voltage precision and power management.

With Maxim Integrated's commitment to quality, the MAX6811LU is a robust and dependable component that adds significant value to any power-sensitive design, ensuring that your systems are protected against unexpected power failures and brown-out conditions.
