MAX6314US31D4

Supervisors Overview

The MAX6314US31D4 is a low-power CMOS microprocessor supervisory circuit designed to monitor power supplies in digital systems. It features a fixed reset threshold voltage of 3.08V and an active-low, bidirectional RESET output compatible with processors like the 68HC11. The device includes a debounced manual reset input and provides a 280ms reset timeout period. It operates within a supply voltage range up to 5.5V and consumes only 5µA of quiescent current. The component is housed in a compact SOT-143-4 package.

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 ensures minimal current consumption during operation
• Fixed threshold voltage eliminates the need for external adjustment components

Supervisors Applications

• Microprocessor (µP) power supply monitoring
• Digital system supervision
• Systems requiring bidirectional reset compatibility

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm RoHS compliance status and lead times directly with suppliers. Check for obsolescence notices as this specific variant may have limited availability. Ensure packaging specifications match assembly requirements. Validate datasheet revisions for accurate electrical characteristics before integration.

Supervisors Selection Notes

Select this component when a bidirectional reset interface is required for microprocessor applications. Consider the fixed 3.08V threshold against system voltage rails. Evaluate the 280ms timeout duration against processor startup requirements. The SOT-143-4 package suits space-constrained designs. Verify operating temperature range suitability for the intended environment.

Supervisors Part Context

The MAX6314 belongs to Maxim Integrated's family of low-power microprocessor supervisory circuits. This series focuses on providing reliable power management without external components. The US suffix indicates the SOT-143 package option. The D4 code specifies the 3.08V threshold variant. Analog Devices acquired Maxim Integrated, influencing branding.

Supervisors Replacement Considerations

Check for MAX6314 variants with different threshold voltages if system voltage differs. Verify pinout compatibility with existing PCB layouts. Consider newer generations from Analog Devices if enhanced features are needed.
