MAX6314US31D2

Supervisors Overview

The MAX6314US31D2 is a low-power CMOS microprocessor supervisory circuit designed to monitor power supplies in digital systems. It features a bidirectional RESET output compatible with processors like the 68HC11 and includes a debounced manual reset input. The device asserts a reset signal when the supply voltage falls below a preset threshold of 3.1V or upon manual assertion. It operates within a temperature range of -40°C to +85°C and utilizes an SOT-143-4 package.

Supervisors Feature Summary

• Bidirectional RESET output for direct connection to microprocessors with bidirectional inputs
• Debounced manual reset input for user-initiated system resets
• Low-power CMOS construction for efficient operation

Supervisors Applications

• Microprocessor (µP) power supply monitoring
• Digital system supervision
• Systems requiring 68HC11 compatibility

Supervisors Procurement Notes

Verify the specific suffix D2 against official Analog Devices documentation to confirm the exact threshold voltage and package variant, as suffixes define electrical characteristics. Confirm RoHS compliance status for the specific revision. Check current availability through authorized distributors, as stock levels fluctuate. Ensure the ordering part number matches the required pinout and thermal specifications for your PCB design.

Supervisors Selection Notes

Select this component when a bidirectional reset interface is required for legacy or specific microcontroller architectures. The fixed 3.1V threshold suits applications where this specific voltage level defines the valid operating window. Consider the SOT-143-4 package size for space-constrained designs. Verify that the manual reset feature meets the system's safety requirements without additional external components.

Supervisors Part Context

This part belongs to the MAX6314 family of supervisory circuits from Maxim Integrated, now part of Analog Devices. The family provides reliable power management solutions for embedded systems. Variants within the series differ primarily by their reset threshold voltages and package options, allowing designers to tailor the supervision parameters to specific rail voltages while maintaining consistent functionality and interface compatibility.

Supervisors Replacement Considerations

Cross-reference with other MAX6314 variants such as MAX6314US26D3 or MAX6314US33D1 if different threshold voltages are needed. Ensure any substitute maintains the bidirectional output capability and SOT-143-4 footprint. Verify that the replacement part supports the same manual reset functionality and operating temperature range.
