Maxim Integrated MAX823LEUK+T Microprocessor Supervisory Circuit

The Maxim Integrated MAX823LEUK+T is a compact and 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 in system monitoring applications. This supervisory circuit is particularly suited for portable and space-constrained applications due to its small SOT-23 package.

Key Features

• Precision Monitoring: The MAX823LEUK+T offers precision voltage monitoring, ensuring that the system microprocessor is reset to a known state during power-up, power-down, or brown-out conditions.
• Manual Reset Input: A manual reset input is provided, allowing for a system reset to be triggered with an external switch or logic signal.
• Low Power Consumption: Designed for power-sensitive applications, this supervisory circuit has a low quiescent current, which helps in extending battery life in portable devices.
• Integrated Watchdog Timer: An on-board watchdog timer improves system reliability by resetting the µP if it fails to strobe within a preset timeout period.
• Reset Timeout: The device features a 140ms min power-on reset timeout period, which ensures that the system µP has sufficient time to stabilize before it starts operation.
• Voltage Threshold Options: A variety of factory-trimmed reset thresholds are available to accommodate different system voltage requirements.

Applications

The MAX823LEUK+T is versatile and can be used in a broad range of applications, including:

• Portable/Battery-Powered Equipment
• Computers and Controllers
• Embedded Systems
• Data Storage Equipment
• Telecommunication Systems
• Industrial Control Systems

With its tight reset threshold accuracy and built-in features, the MAX823LEUK+T from Maxim Integrated is an ideal choice for system designers looking to enhance the reliability and performance of their microprocessor-based systems.
