MAX6314US26D2+T

Supervisors Overview

The MAX6314US26D2+T is a low-power CMOS microprocessor supervisory circuit designed to monitor power supplies in digital systems. It features a bidirectional RESET output compatible with 68HC11 processors and includes a debounced manual reset input. The device asserts a reset signal when the supply voltage falls below the 2.63V threshold or upon manual assertion, maintaining the state for a 200ms timeout period after voltage recovery. Packaged in a compact SOT-143-4 format, it eliminates external components.

Supervisors Feature Summary

• Bidirectional RESET output enables direct connection to microprocessors with bidirectional reset inputs, such as the 68HC11 family.
• Integrated debounced manual reset input allows for user-initiated system resets without external hardware.
• Fixed threshold supervision ensures reliable operation by asserting reset signals only when supply voltage drops below the preset level.

Supervisors Applications

• Microprocessor (µP) power supply monitoring
• Digital system voltage supervision
• Systems requiring 68HC11 compatibility

Supervisors Procurement Notes

Verify component authenticity through authorized Analog Devices distributors due to limited availability status. Confirm RoHS compliance markings on the package, as suffixes indicate lead-free construction. Cross-reference datasheet revision dates to ensure parameter accuracy. Check for obsolescence notices before finalizing procurement plans.

Supervisors Selection Notes

Select this component for applications requiring bidirectional interface compatibility with legacy microcontrollers like the 68HC11. Ensure the 2.63V threshold aligns with the target system's minimum operating voltage requirements. Verify that the SOT-143-4 package fits the PCB layout constraints. Consider the 200ms delay time against system startup timing needs.

Supervisors Part Context

Part of the MAX6314 series of low-power CMOS supervisory circuits from Maxim Integrated. Designed specifically for microprocessor reset applications, offering a cost-effective solution by integrating essential functions into a single small package. The series provides various threshold voltages to suit different supply rail requirements.

Supervisors Replacement Considerations

Check for MAX6314 variants with different threshold voltages if system voltage levels differ. Verify pinout compatibility with existing designs. Consult official substitution lists for end-of-life management strategies.
