Maxim Integrated MAX825TEUK+T Microprocessor Supervisory Circuit

The Maxim Integrated MAX825TEUK+T is a 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 a 3.3V power supply.

Key Features:

• Voltage Monitoring: This device keeps a watchful eye on the system's power supply, ensuring that the voltage does not fall below the minimum threshold which can lead to system instability.
• Power-On Reset: The MAX825TEUK+T generates a reset signal whenever the supply voltage drops below the reset threshold, ensuring that the µP starts in a known state.
• Manual Reset: A manual reset feature allows for an external signal to trigger a reset, offering additional control to system designers.
• Low Power Consumption: With its low power demands, this supervisory circuit is ideal for portable and battery-operated applications.
• Compact SOT-23 Packaging: The small size of the SOT-23 package makes it suitable for space-constrained applications.

Applications:

• Computers and Controllers
• Intelligent Instruments
• Portable/Battery-Powered Equipment
• Embedded Systems

The MAX825TEUK+T is designed to maintain system integrity and prevent data corruption during power failures or unexpected behavior by providing a robust set of features. It asserts a reset signal until the system voltage reaches a stable and acceptable level and maintains the reset for a period after the supply has stabilized, ensuring a proper system restart.

Maxim Integrated's commitment to quality and reliability is evident in devices like the MAX825TEUK+T, which is engineered to meet the stringent demands of modern electronic systems. By integrating this supervisory circuit into your design, you can enhance system reliability, reduce component count, and ensure a more robust performance under variable power conditions.
