Maxim Integrated MAX825SEUK Microprocessor Supervisory Circuit

The MAX825SEUK from Maxim Integrated is a compact, highly efficient 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 systems that require voltage monitoring and battery control functions.

This supervisory circuit is particularly suitable for portable and space-constrained applications due to its small SOT-23 package. It offers a variety of features that ensure system stability through power-up, operation, and power-down phases. The MAX825SEUK provides a precision voltage monitor with a factory-set reset threshold voltage, and its reset output is available in both active-low and active-high configurations, ensuring compatibility with a wide range of microprocessors and digital systems.

Key Features:

• Precision Monitoring: Factory-set reset threshold voltages ensure accurate monitoring of the power supply voltage, which is critical for maintaining system reliability.
• Manual Reset: A manual reset input allows the user or an external device to initiate a system reset, providing additional control over the system's operation.
• Low Power Consumption: Designed for energy-sensitive applications, this device consumes minimal power, thereby extending battery life in portable applications.
• Reset Timeout: The MAX825SEUK features an internally programmed timeout period that provides a delay before the reset signal is issued, allowing the power supply to stabilize.
• Compact Package: The small SOT-23 package saves valuable board space, making it ideal for use in space-constrained applications such as handheld devices.

Applications for the MAX825SEUK include portable devices, computers, controllers, and intelligent instruments where reliable voltage monitoring is critical. Its ease of integration, combined with Maxim Integrated's reputation for high-quality electronic components, makes the MAX825SEUK a smart choice for designers looking to enhance system stability and extend product life.
