Maxim Integrated Product: MAX6349YPUT-T Overview

The MAX6349YPUT-T is a 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 with a single 3.3V power-supply voltage.

This device performs a critical function in ensuring system stability by providing a reset signal to the µP during power-up, power-down, and brownout conditions. The reset signal maintains the processor in a reset state until the system voltage stabilizes within acceptable operating limits. This feature significantly enhances system reliability as it prevents the µP from executing code erratically during uncertain power conditions.

Key Features:

• Precision Monitoring: The MAX6349YPUT-T is capable of monitoring a 3.3V power supply with a precision threshold, ensuring accurate reset signaling.
• Low Power Consumption: Designed for power-sensitive applications, this supervisory circuit has a low quiescent current draw, which helps to conserve battery life in portable devices.
• Manual Reset Input: It includes a manual reset input that allows for a reset to be triggered by external factors or user input, providing additional system control.
• Compact Package: The device comes in a small SOT23-6 package, making it ideal for space-constrained applications.
• Extended Temperature Range: The MAX6349YPUT-T operates over an extended temperature range, making it suitable for industrial applications.

The MAX6349YPUT-T is commonly utilized in a variety of applications, including portable/battery-powered equipment, embedded controllers, computers, and other digital systems that require a stable and reliable reset signal for proper operation.

Maxim Integrated's commitment to innovation is evident in the MAX6349YPUT-T, which simplifies design, reduces component count, and ensures system integrity through its precise monitoring and reset capabilities. By choosing the MAX6349YPUT-T, designers can ensure their systems maintain optimal functionality even in the face of power supply irregularities.
