MAX6305UK00D3-T

Supervisors Overview

The MAX6305UK00D3-T is a CMOS microprocessor supervisory circuit designed to monitor multiple power supplies. It features two monitored inputs with adjustable or selectable voltage thresholds, allowing for flexible configuration in systems requiring dual-voltage supervision. The device provides an active-low reset output via an open-drain or open-collector interface. It operates within a supply voltage range up to 5.5V and includes a minimum reset timeout of 140ms. The component is housed in a compact SOT-23-5 surface-mount package.

Supervisors Feature Summary

• Monitors two independent power supply rails simultaneously
• Features adjustable or selectable voltage threshold levels
• Provides an active-low reset signal through an open-drain output

Supervisors Applications

• Personal computer system power monitoring
• Portable electronic devices requiring low supply current
• Systems needing protection against out-of-specification voltage conditions

Supervisors Procurement Notes

Verify the specific suffix D3 against the manufacturer's official datasheet to confirm the exact threshold configuration and revision status. Confirm RoHS compliance and lead-free status as per the latest product documentation. Check for obsolescence notices from Analog Devices Inc., as this part may be subject to discontinuation or limited availability.

Supervisors Selection Notes

Select this component when dual-supervision capability is required within a small form factor. Ensure the application environment stays within the specified operating temperature range. Verify that the open-drain output type matches the downstream logic requirements. Consider the 140ms minimum reset timeout duration relative to system startup timing constraints.

Supervisors Part Context

This part belongs to the MAX6305–MAX6313 series of CMOS microprocessor supervisory circuits manufactured by Maxim Integrated, now part of Analog Devices Inc. These devices are engineered to ignore fast transients on monitored supplies while asserting a reset if voltages fall outside programmed thresholds. The series is optimized for portable applications due to low supply current consumption and small package size.

Supervisors Replacement Considerations

Consult the official MAX6305 datasheet for confirmed substitute part numbers within the same family. Verify pin compatibility and electrical specifications before substitution.
