MAX6314US46D2-T

Supervisors Overview

The MAX6314US46D2-T is a low-power CMOS microprocessor supervisory circuit designed to monitor power supplies in µP and digital systems. It features a bidirectional RESET output compatible with processors like the 68HC11. The device monitors a single input with a fixed threshold voltage of 4.63V. It includes a debounced manual reset input and operates within a supply voltage range up to 5.5V. The component functions across an extended temperature range from -40°C to +85°C and is housed in a compact SOT-143 package.

Supervisors Feature Summary

• Bidirectional RESET output enables direct connection to microprocessors with bidirectional reset inputs, such as the 68HC11.
• Integrated debounced manual reset input allows for user-initiated system resets without external components.
• Eliminates the need for external adjustments or discrete components by providing factory-set reset thresholds.

Supervisors Applications

• Monitoring power supplies in microprocessor-based systems
• Providing reset signals for 68HC11 and similar bidirectional-compatible microprocessors
• Ensuring circuit reliability in digital systems through automated power supervision

Supervisors Procurement Notes

Verify the specific suffix D2 against official Analog Devices documentation to confirm the exact threshold voltage and package variant. Confirm RoHS compliance status for the specific manufacturing lot. Check current availability as distribution channels may list limited stock or obsolete status. Ensure the bidirectional output requirement matches the target microprocessor interface specifications before finalizing procurement.

Supervisors Selection Notes

Select this component when a bidirectional reset interface is required for compatibility with legacy or specific microprocessor architectures like the 68HC11. It is suitable for applications needing a fixed 4.63V threshold without adjustable programming. Consider the SOT-143 package size constraints and the operational temperature range requirements. Verify that the manual reset feature aligns with the system's safety and control logic design.
