MAX6314US46D3

Supervisors Overview

The MAX6314US46D3+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 microprocessors like the 68HC11 and includes a debounced manual reset input. The device asserts a reset signal when the supply voltage falls below the preset threshold of 4.63V or upon manual assertion. Key electrical parameters include a maximum supply voltage of 5.5V, a reset delay time of 200ms, and an operating current of 5µA. It operates within a temperature range of -40°C to +85°C with 1.8% accuracy.

Supervisors Feature Summary

• Bidirectional RESET output enables direct connection to microprocessors with bidirectional reset inputs
• Integrated debounced manual reset input for user-initiated system resets
• Low-power CMOS design suitable for portable applications with minimal supply current consumption

Supervisors Applications

• Microprocessor (µP) power supply monitoring
• Digital system supervision
• Systems requiring bidirectional reset compatibility such as 68HC11 architectures

Supervisors Procurement Notes

Verify the complete part number including suffixes such as +T for tape-and-reel packaging. Confirm RoHS compliance status (+ suffix indicates lead-free). Ensure the specific threshold voltage variant matches the design requirement. Check manufacturer documentation for handling precautions and storage conditions relevant to the SOT-143 package.

Supervisors Selection Notes

Select this component when a bidirectional reset interface is required for specific microprocessor families. The fixed 4.63V threshold suits applications where the supply rail requires monitoring at this specific level. Consider the 200ms timeout period against system startup requirements. Evaluate the 5µA quiescent current against battery life constraints in portable designs.

Supervisors Part Context

This device belongs to the MAX6314 series of supervisory circuits from Analog Devices/Maxim Integrated. The series offers various fixed threshold voltages to accommodate different supply rails. The US package designation indicates the SOT-143 form factor. The D3 suffix typically denotes the specific threshold voltage version within the product line.

Supervisors Replacement Considerations

Cross-reference with other MAX6314 variants having different threshold voltages if the supply level differs. Verify pinout compatibility with alternative supervisory ICs before substitution. Ensure bidirectional output capability is maintained if replacing with open-drain alternatives.
