MAX6314US26D4

Supervisors Overview

The MAX6314US26D4+T 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. Key parameters include a threshold voltage of 2.63 V, a reset delay time of 200 ms, and a maximum supply voltage of 5.5 V. The device operates within a temperature range of -40°C to +85°C, consumes 5 µA of quiescent current, and offers an accuracy of 1.8%. It includes a manual reset input and is housed in an SOT-143-4 package.

Supervisors Feature Summary

• Bidirectional RESET output for direct connection to microprocessors with bidirectional reset inputs
• Manual reset input capability for user-initiated system resets
• Low-power CMOS design suitable for battery-operated applications

Supervisors Applications

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

Supervisors Procurement Notes

Verify the specific suffix D4 against official Analog Devices documentation to confirm exact threshold and timing specifications, as datasheets may list variants like D3 or D2. Confirm RoHS compliance status and packaging options such as cut tape or reel availability through authorized distributors. Ensure the component matches the required operating temperature range and package type for your design.

Supervisors Selection Notes

Select this component when a bidirectional reset interface is required for legacy or specific microprocessor architectures. Consider the 2.63 V threshold if it aligns with the target supply rail's minimum operating voltage. Evaluate the 200 ms timeout period against system startup requirements. The low quiescent current makes it suitable for power-sensitive designs compared to higher consumption alternatives.

Supervisors Part Context

The MAX6314 belongs to the Maxim Integrated (now Analog Devices) family of low-power supervisory circuits. This series is characterized by its ability to eliminate external components and adjustments while providing reliable reset signals. The US26 variant specifically targets applications needing a precise 2.63 V threshold with bidirectional output capabilities.

Supervisors Replacement Considerations

Check for MAX6314US26D3+T or other suffixes within the MAX6314 series that may offer identical electrical characteristics but different packaging or environmental ratings. Verify pinout compatibility before substitution.
