MAX6364HUT31-T

Overview

The MAX6364HUT31-T is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 1.2V to 5.5V and features a fixed threshold voltage of 3.08V for monitoring input lines. The device provides an active-low, push-pull output and includes a manual reset input capability. It incorporates a watchdog timer with a timeout period of 1.4 seconds and offers battery backup switching functionality. Packaged in a compact SOT-23-6 format, it supports operation temperatures from -40°C to +85°C with a quiescent current of 15µA.

Feature Summary

• Integrates a watchdog timer with configurable timeout periods for system reliability
• Provides manual reset input functionality for user-initiated control
• Includes battery backup switch to manage power source transitions
• Features active-low push-pull output driver for direct logic interfacing

Applications

• Portable electronic devices requiring low-power voltage supervision
• Battery-operated systems needing backup power management
• Microprocessor-based circuits requiring watchdog protection
• Industrial control systems operating in extended temperature ranges

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing components. Confirm the manufacturer designation matches Analog Devices or Maxim Integrated to ensure authenticity. Check RoHS compliance documentation for environmental regulations relevant to your region. Validate that the SOT-23-6 package dimensions align with your PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when a fixed 3.08V threshold is required for system monitoring. Consider the integrated watchdog timer if software fault detection is necessary without external components. The low quiescent current makes it suitable for battery-powered applications where energy efficiency is critical. Ensure the input voltage range covers your system's operational limits to prevent false resets during normal operation.

Part Context

This part belongs to the MAX636x series of supervisory circuits designed for monitoring voltage levels in digital systems. The series offers various threshold voltages and output configurations to suit different application needs. Analog Devices acquired Maxim Integrated, consolidating these product lines under one manufacturer. The MAX6364 variant specifically adds manual reset and watchdog features compared to basic supervisors.

Replacement Considerations

Check for MAX6364HUT31+ as a potential lead-free alternative if the '-T' reel specification differs. Verify pin compatibility with other MAX636x family members offering similar thresholds. Ensure any substitute maintains the same SOT-23-6 package outline for mechanical interchangeability.
