Maxim Integrated MAX6414UK31 Overview

The MAX6414UK31 is a highly reliable and precise microprocessor (µP) supervisory circuit designed by Maxim Integrated to monitor power supplies in 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.

Key Features

• Voltage Monitoring: The device is designed to keep a vigilant watch over the system voltage, ensuring that it remains within operational thresholds. It features a preset V_CC reset threshold of 3.1V, which is ideal for 3.3V-powered systems.
• Compact Design: The MAX6414UK31 comes in a space-saving SOT23 package, making it suitable for use in systems where board space is at a premium.
• Manual Reset Input: It includes a manual reset input, allowing users to trigger a system reset with an external switch or logic signal.
• Low Power Consumption: This device is designed for low power consumption, which is critical for battery-operated and portable devices, ensuring minimal impact on overall system power.
• Reset Timeout: The MAX6414UK31 has an internally fixed reset timeout period, which provides a predictable delay before the system is allowed to resume operation after a reset event.
• Immune to Short V_CC Transients: The device is designed to ignore short-duration transients on the V_CC line, which helps prevent false resets from occurring due to line noise or brief power interruptions.

Applications

The MAX6414UK31 is suitable for a wide range of applications, including:

• Portable/Battery-Powered Equipment
• Computers and Controllers
• Embedded Systems
• Data Storage Equipment
• Telecommunications Systems

Conclusion

In summary, the MAX6414UK31 from Maxim Integrated is a robust and compact µP supervisory circuit that offers precise monitoring of system voltages, a manual reset feature, and low power consumption, all in a small SOT23 package. Its ability to withstand voltage transients and its ease of integration make it an excellent choice for designers looking to enhance the reliability and performance of their digital systems.
