MAX6306UK44D2+T

Supervisors Overview

The MAX6306UK44D2+T is a CMOS microprocessor supervisory circuit designed to monitor multiple power supplies. It operates within a supply voltage range of up to 5.5V and features a fixed reset threshold voltage of 4.4V. The device provides an active-low, open-drain output with a manual reset input capability. It is housed in a compact SOT-23-5 surface-mount package and supports operation across industrial temperature ranges.

Supervisors Feature Summary

• Monitors multiple power supply inputs to assert system reset if any monitored supply falls outside the programmed threshold
• Features a manual reset input for external control of the reset state
• Designed to ignore fast transients on monitored supplies to prevent false resets

Supervisors Applications

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

Supervisors Procurement Notes

Verify component authenticity through authorized Analog Devices or Maxim Integrated distributors. Confirm RoHS compliance status and check for obsolescence notices. Ensure the specific suffix matches required threshold voltages and package variants. Request original manufacturer documentation for final technical validation before integration.

Supervisors Selection Notes

Select this part when multi-input supervision is required for critical logic levels. Verify that the fixed 4.4V threshold aligns with the target supply rail. Consider the SOT-23-5 footprint constraints and ensure the manual reset pin is utilized correctly in the schematic design for proper system initialization.

Supervisors Part Context

This component belongs to the MAX6305–MAX6313 family of 5-pin, multiple-input, programmable reset ICs. These devices are engineered for portable applications due to their low supply current consumption and small physical size. The series offers factory-programmed thresholds ranging from 2.5V to 5.0V in precise increments.

Supervisors Replacement Considerations

Cross-reference with other MAX6306 variants having identical SOT-23-5 packaging and compatible threshold specifications. Verify functional equivalence regarding transient immunity and manual reset capabilities before substitution.
