Maxim Integrated MAX6316MUK29CY Product Overview

The MAX6316MUK29CY is a highly reliable, low-power microprocessor (μP) supervisory circuit designed by Maxim Integrated 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 system monitoring applications.

This supervisory circuit ensures that the μP is reset to a known state during power-up, power-down, or brown-out conditions. The MAX6316MUK29CY comes with a preset threshold voltage of 2.9V, which makes it suitable for monitoring 3.3V power supplies and other voltage rails close to this threshold.

Key Features

• Precision Monitoring: The device features a factory-trimmed reset threshold voltage, ensuring accurate monitoring of the power supply voltage without the need for external adjustments.
• Low Power Consumption: With its low supply current of only 1.2μA, the MAX6316MUK29CY is ideal for battery-powered equipment, contributing to extended battery life.
• Manual Reset Input: It includes a manual reset input that allows for a system reset to be triggered with an external pushbutton or logic signal.
• Reset Timeout: The device offers a 140ms min reset active timeout period, providing sufficient time for the system to stabilize during power-up or after a disturbance.
• Compact Package: The supervisory circuit is available in a space-saving SOT-23 package, making it suitable for use in systems where board space is at a premium.

Applications

The MAX6316MUK29CY is versatile and can be used in a wide range of applications, including:

• Portable/Battery-Powered Equipment
• Computers and Controllers
• Embedded Systems
• Data Storage Systems
• Medical Devices
• Automotive Systems

With its precision voltage monitoring and low-power operation, the MAX6316MUK29CY is an excellent choice for designers looking to enhance system reliability without sacrificing power efficiency. Its ease of integration and robust feature set make it a go-to solution for safeguarding critical μP systems from unpredictable power supply conditions.
