MAX6306UK31D3+T

Supervisors Overview

The MAX6306UK31D3+T is a CMOS microprocessor supervisory circuit designed to monitor power supply voltages. It features a fixed reset threshold voltage of 3.08V and includes a manual reset input for system control. The device operates within an extended temperature range of -40°C to +85°C and draws low supply current, making it suitable for portable applications. It asserts a system reset if the monitored supply falls outside the programmed threshold. The component is housed in a compact SOT-23-5 package (MO-178AA) with five pins, ensuring minimal board space usage while providing reliable voltage supervision.

Supervisors Feature Summary

• Monitors power supply voltage and asserts reset when thresholds are exceeded
• Includes manual reset input for direct system control
• Designed to ignore fast transients on monitored supplies
• Operates in extended industrial temperature ranges

Supervisors Applications

• Personal computer systems monitoring multiple power rails
• Portable electronic devices requiring low power consumption
• Embedded systems needing reliable voltage supervision
• Industrial equipment requiring transient immunity

Supervisors Procurement Notes

Verify that the ordering suffix matches the exact threshold voltage and package type required for your design. Confirm RoHS compliance status and lead-free specifications with the supplier or manufacturer documentation before purchase. Ensure the component version aligns with the specific electrical characteristics needed for your application to avoid integration issues.

Supervisors Selection Notes

Select this part when a fixed 3.08V reset threshold is required for single-supervision applications. Consider the manual reset feature if external user intervention is needed to trigger a reset state. Evaluate the SOT-23-5 package constraints against available PCB space. Compare operating temperature ranges against environmental conditions to ensure reliability under all expected operational scenarios.

Supervisors Part Context

This component belongs to the MAX6305–MAX6313 family of 5-pin, multiple-input, programmable reset ICs manufactured by Maxim Integrated. These devices are specifically engineered for microprocessor supervisory roles, offering factory-programmed thresholds from 2.5V to 5.0V. The family emphasizes low power consumption and robust performance in portable and personal computing environments.

Supervisors Replacement Considerations

Check for compatible parts within the MAX6305–MAX6313 series that offer similar threshold voltages and package types. Verify pinout compatibility and electrical parameter alignment before substitution. Consult official cross-reference lists for confirmed equivalent components.
