The MAX823MUK AAAJ from Maxim Integrated is a compact, highly-reliable microprocessor (µP) supervisory circuit designed to monitor power supplies and microprocessor activity in digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used in systems with +2.5V, +3V, +3.3V, and +5V-powered microprocessors.

Key Features

• Precision Monitoring: This device features precision voltage monitoring that ensures the system's microprocessor always operates under optimal power conditions. It guards against undervoltage conditions that could lead to system errors and instability.
• Reset Output: The MAX823MUK AAAJ provides a reset output during power-up, power-down, and brownout conditions. The reset signal remains asserted for a minimum of 140ms after VCC has risen above the reset threshold, ensuring a proper system reset.
• Low Power Consumption: Designed for power-sensitive applications, this supervisory circuit consumes minimal power, thereby contributing to the overall energy efficiency of the system it is monitoring.
• Compact SOT23 Packaging: The device comes in a small, 5-pin SOT23 package, making it suitable for space-constrained applications without compromising functionality.
• Manual Reset Feature: It includes a manual reset feature that allows for a system reset to be manually triggered, providing an additional layer of control for system maintenance or debugging.
