MAX6314US31D3

Supervisors Overview

The MAX6314US31D3 is a low-power CMOS microprocessor supervisory circuit designed to monitor power supplies in microprocessor and digital systems. It features a bidirectional RESET output compatible with processors like the 68HC11, eliminating external components. The device operates within a supply voltage range up to 5.5V and includes a manual reset input for system control. It provides a fixed threshold voltage of 3.08V with a reset delay time of 200ms. The circuit draws only 5µA of operating supply current, ensuring minimal power consumption during standby modes.

Supervisors Feature Summary

• Bidirectional RESET output enables direct connection to microprocessors with bidirectional reset inputs
• Manual reset input allows for user-initiated system resets independent of voltage levels
• Low operating supply current supports extended battery life in portable applications

Supervisors Applications

• Microprocessor system power supervision
• Digital system voltage monitoring
• Portable electronic devices requiring low power consumption

Supervisors Procurement Notes

Verify the specific suffix D3 against official Analog Devices documentation to confirm package type and temperature range. Ensure the part number matches the exact threshold voltage required for your application, as variations exist within the MAX6314 family. Confirm RoHS compliance status if environmental regulations apply to your manufacturing process.

Supervisors Selection Notes

Select this component when a bidirectional reset interface is necessary for compatibility with legacy or specific microcontroller architectures. Consider the 3.08V threshold relative to your system's nominal voltage to ensure proper reset assertion during brown-out conditions. Evaluate the 200ms delay against your processor's startup requirements to prevent premature operation.

Supervisors Part Context

The MAX6314 series belongs to Maxim Integrated's line of microprocessor supervisory circuits. These devices are engineered to provide reliable reset signals without requiring external timing components. The US31 variant specifically denotes the 3.08V threshold setting within the broader MAX6314 product family, targeting applications where precise voltage monitoring is critical for system stability.

Supervisors Replacement Considerations

Cross-reference with other MAX6314 variants such as MAX6314US33D3 or MAX6314US37D3 if different threshold voltages are needed. Verify pinout compatibility before substitution. Check datasheet revisions to ensure functional equivalence regarding reset delay and output characteristics.
