MAX6314US41D3

Supervisors Overview

The MAX6314US41D3 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 asserts a reset signal when the supply voltage falls below a preset threshold of 4.1V or when manual reset is asserted. It includes a debounced manual reset input and provides a fixed timeout period after voltage recovery. The component operates within a supply voltage range up to 5.5V, consumes 5µA of quiescent current, and functions across an industrial temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Bidirectional RESET output for direct connection to microprocessors with bidirectional reset inputs
• Debounced manual reset input for user-initiated system resets
• Low-power CMOS design ensuring minimal current consumption during operation
• Fixed reset threshold voltage eliminates need for external adjustments

Supervisors Applications

• Microprocessor (µP) power supply monitoring
• Digital system supervision
• Systems utilizing 68HC11 or similar bidirectional reset interface controllers

Supervisors Procurement Notes

Verify the specific suffix variant (e.g., D1, D2, D3) against the required reset threshold voltage, as these denote different trip points. Confirm RoHS compliance status, as some variants are lead-free while others may not be. Check lifecycle status, as certain models in this series are marked obsolete or restricted. Ensure the package type matches the PCB footprint requirements.

Supervisors Selection Notes

Select this component when a bidirectional reset interface is required for compatibility with specific microcontrollers. Choose based on the precise voltage threshold needed for the target supply rail. Consider the low quiescent current for battery-operated applications. Verify that the fixed timeout period meets the system's startup timing requirements without additional external components.

Supervisors Part Context

The MAX6314 belongs to Maxim Integrated's family of low-power microprocessor supervisory circuits. These devices are engineered to replace discrete resistor-capacitor networks and comparators, simplifying board design. The series offers various fixed thresholds and package options to suit diverse embedded system architectures.

Supervisors Replacement Considerations

Substitutes must match the bidirectional output capability and the 4.1V threshold. Verify pinout compatibility with SOT-143 packages. Cross-reference with other MAX6314 variants if the threshold voltage differs.
