Maxim Integrated MAX825LEXK+T Microprocessor Supervisory Circuit

The Maxim Integrated MAX825LEXK+T 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 for system monitoring. This component is an essential solution for managing system health and ensuring stability across various applications.

This supervisory circuit is specifically engineered to maintain system integrity through monitoring. It functions by asserting a reset signal whenever the VCC supply voltage declines below a preset threshold, keeping it asserted until the supply voltage returns to an acceptable level and a specified period has passed. This reset signal ensures that the µP and other critical system components are reset simultaneously, establishing a clean start for the system once the power returns to a stable state.

The MAX825LEXK+T features a factory-trimmed reset threshold voltage, which is preset to a standard value suitable for most applications, ensuring compatibility without the need for external adjustments. The device's reset output is available in both push-pull and open-drain configurations, providing flexibility for interfacing with different types of µP and logic circuits.

With its small SOT23 package, the MAX825LEXK+T is space-efficient, making it ideal for use in systems where board space is at a premium. Its low power consumption is also beneficial for portable and battery-operated devices, ensuring minimal impact on overall system power reserves.

Key features of the MAX825LEXK+T include:

• Factory-trimmed VCC reset threshold for ease of use
• Low power consumption suitable for battery-operated devices
• Compact SOT23 package for space-constrained applications
• Guaranteed reset valid to VCC = 1V for low-voltage operations
• Immune to short VCC transients for robust performance
• Push-pull or open-drain reset output options for versatile interfacing

Overall, the Maxim Integrated MAX825LEXK+T is an ideal choice for designers looking for a simple, effective, and space-saving solution for voltage monitoring and system reset functions. Its reliability and ease of integration make it a go-to component for a wide range of digital systems and applications.
