MAX6306UK31D3

Supervisors Overview

The MAX6306UK31D3 is a CMOS microprocessor supervisory circuit designed to monitor multiple power supplies. It features a manual reset input and an active-low open-drain output. The device asserts a system reset if any monitored supply falls outside the programmed threshold, specifically ignoring fast transients. It operates within a maximum supply voltage of 5.5V and includes a reset delay time of 1.57 seconds. The component is housed in a SOT-23-5 package.

Supervisors Feature Summary

• Monitors more than one power supply for system integrity
• Features a manual reset input for user control
• Designed to ignore fast transients on monitored supplies

Supervisors Applications

• Personal computer systems monitoring 5V and 3.3V rails
• Portable applications requiring low supply current
• Microprocessor supervisory circuits

Supervisors Procurement Notes

Verify the specific suffix (e.g., D3 vs D4) against official datasheets as it determines the exact reset threshold voltage. Confirm RoHS compliance status and lead-free availability with the manufacturer or authorized distributors. Check for obsolescence notices or lifecycle changes before procurement planning.

Supervisors Selection Notes

Select this component when multi-input voltage supervision is required in space-constrained designs. Ensure the fixed reset threshold matches the target supply voltage. Consider the SOT-23-5 package size for portable applications. Verify that the manual reset feature aligns with the system's reset logic requirements.

Supervisors Part Context

Part of the MAX6305–MAX6313 series of 5-pin, multiple-input, programmable reset ICs from Maxim Integrated. These devices are optimized for monitoring dual voltage rails in computing and portable electronics, offering low quiescent current and transient immunity.

Supervisors Replacement Considerations

Check for direct substitutes within the MAX6305–MAX6313 family with matching threshold voltages. Verify pinout compatibility and package dimensions (SOT-23-5) for board-level replacements.
