MAX6314US26D3

Supervisors Overview

The MAX6314US26D3+T is a low-power CMOS microprocessor supervisory circuit designed for monitoring power supplies in digital systems. It features a bidirectional output compatible with processors like the 68HC11 and includes a debounced manual reset input. The device asserts a reset signal when the supply voltage falls below a preset threshold of 2.63 V or upon manual activation. It operates within a supply range up to 5.5 V, consumes 5 µA, and maintains an accuracy of 1.8%. The component supports a 200 ms reset timeout and functions across temperatures from -40°C to +85°C.

Supervisors Feature Summary

• Bidirectional output interface enables direct connection to microprocessors with bidirectional reset inputs
• Integrated debounced manual reset input allows for user-initiated system resets
• Low quiescent current consumption supports battery-operated applications
• Factory-set threshold voltage eliminates external component adjustments

Supervisors Applications

• Microprocessor (µP) power supply monitoring
• Digital system voltage supervision
• Systems requiring bidirectional reset compatibility

Supervisors Procurement Notes

Verify the complete part number including suffixes such as +T for tape-and-reel packaging. Confirm RoHS compliance status through official documentation. Ensure the specific threshold voltage variant matches design requirements. Check manufacturer datasheets for pinout and electrical characteristics before integration.

Supervisors Selection Notes

Select this component for designs requiring bidirectional reset signaling to legacy microcontrollers. The fixed 2.63 V threshold suits 3.3 V or 5 V logic systems. Consider the SOT-143 package for space-constrained PCB layouts. Verify that the 200 ms timeout meets system startup timing requirements.

Supervisors Part Context

This device belongs to the MAX6314 series of low-power CMOS supervisory circuits. It is manufactured by Analog Devices Inc., formerly Maxim Integrated. The series focuses on providing reliable power management solutions with minimal external components for embedded applications.

Supervisors Replacement Considerations

Consult official substitution guides for equivalent parts. Verify pin compatibility and threshold voltage alignment. Ensure bidirectional output functionality is maintained if replacing with similar supervisory ICs.
