Maxim Integrated MAX6823SUK+T Microprocessor Supervisory Circuit

The MAX6823SUK+T from Maxim Integrated is a compact, highly reliable microprocessor (µP) supervisory circuit designed to monitor power supplies in µP and digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used with +5V-powered circuits.

This supervisory circuit is particularly suitable for use in portable electronics, computers, controllers, and intelligent instruments where maintaining the integrity of the operating system is critical. It ensures that the µP starts up in a known state and monitors the power supply to prevent code execution errors during low-voltage conditions.

Key Features:

• Voltage Monitoring: The MAX6823SUK+T keeps a watchful eye on the system voltage, providing a reset signal to the microprocessor during power-up, power-down, and brownout conditions. The reset signal remains asserted until the system voltage stabilizes and maintains the proper reset timeout period after V<sub>CC rises above the reset threshold.
• Precision Reset Threshold: This device has a factory-set reset threshold voltage, which is trimmed to high accuracy. This precision ensures reliable operation without the need for external adjustments.
• Low Power Consumption: Designed for power-sensitive applications, the MAX6823SUK+T consumes minimal power, which is crucial for extending battery life in portable devices.
• Manual Reset Input: An additional feature is the manual reset input, which allows for a reset to be triggered with an external switch or logic signal, providing an extra layer of system control.
• Compact Package: The device comes in a small SOT-23 package, making it ideal for space-constrained applications.
• Temperature Range: It operates over an extended temperature range, ensuring reliability across various environmental conditions.

The MAX6823SUK+T is an essential component for systems that require a reliable and automatic reset capability. Its ease of integration and robust feature set make it a popular choice among engineers and designers looking to enhance system stability and performance.

Overall, Maxim Integrated's MAX6823SUK+T provides a simple and efficient solution for power monitoring and reset management, ensuring that digital systems operate within their intended parameters, thus safeguarding the integrity of the applications they control.
