MAX6314US44D1

Supervisors Overview

The MAX6314US44D1 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 inputs like the 68HC11, eliminating external components. The device includes a debounced manual reset input and offers precision factory-set VCC reset thresholds with ±1.8% accuracy at +25°C. It operates within a supply voltage range up to 5.5V, consumes only 5µA of supply current, and provides immunity to short VCC transients.

Supervisors Feature Summary

• Bidirectional RESET output simplifies interface to microprocessors with bidirectional reset I/Os
• Precision factory-set VCC reset thresholds ensure reliable monitoring without adjustments
• Debounced manual reset input allows for user-initiated system resets
• Immune to short VCC transients to prevent false triggering

Supervisors Applications

• Computers
• Controllers
• Intelligent Instruments
• Critical µP and µC Power Monitoring
• Portable/Battery-Powered Equipment

Supervisors Procurement Notes

Verify the specific threshold voltage suffix (e.g., US44) against the design requirement, as the MAX6314 series utilizes different codes for various voltage levels. Confirm package availability and lead times through authorized distributors, as stock levels may vary. Ensure the component meets RoHS compliance standards if required by the target application environment.

Supervisors Selection Notes

Select this component when a bidirectional reset interface is necessary for compatibility with legacy or specific microprocessor architectures. The low quiescent current makes it suitable for battery-powered applications where power efficiency is critical. Verify that the fixed reset threshold matches the minimum operating voltage of the monitored supply rail to ensure proper system initialization.

Supervisors Part Context

This part belongs to the MAX6314 family of microprocessor supervisory circuits from Analog Devices/Maxim Integrated. The family is characterized by its small SOT143 package and pin-compatibility with older devices like the MAX811. It serves as a cost-effective solution for ensuring system reliability by monitoring power supply integrity in embedded digital systems.

Supervisors Replacement Considerations

The MAX6314 is pin-compatible with the MAX811. When replacing legacy parts, verify that the bidirectional output functionality aligns with the original circuit design requirements.
