Maxim Integrated's MAX824MEUK+ Microprocessor Supervisory Circuit

The MAX824MEUK+ from Maxim Integrated is a highly reliable and compact 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 ensures that the µP is reset to a known state during power-up, power-down, or brown-out conditions. The MAX824MEUK+ features a combination of functions such as reset output during power-up, power-down, and brown-out conditions, and a manual reset input, making it a versatile component for system stability.

Key features of the MAX824MEUK+ include:

• Power Supply Monitoring: Precise monitoring to ensure the power supply remains within acceptable limits.
• Reset Timeout: It offers a 140ms min power-on reset timeout, which provides the system enough time to stabilize before the processor starts operating.
• Manual Reset Input: A dedicated input that allows for a manual reset, giving additional control to the system designer or operator.
• Low Power Consumption: The device operates with a low quiescent current, making it suitable for power-sensitive applications.
• Compact SOT-23 Packaging: The small size of the 5-pin SOT-23 package allows for efficient use of board space, which is crucial in space-constrained applications.

The MAX824MEUK+ operates over a wide voltage range from 1.2V to 5.5V, making it suitable for use in a variety of systems, from battery-powered devices to complex digital circuits. The device's active-low reset output ensures compatibility with most microprocessors, requiring minimal interfacing components.

With its built-in features, the MAX824MEUK+ provides a robust solution for system management and reliability. Whether it's used in computers, controllers, intelligent instruments, or portable consumer products, this supervisory circuit from Maxim Integrated stands out as a top choice for designers looking to enhance system integrity and prevent data corruption due to power anomalies.
