MAX6305UK00D1

Supervisors Overview

The MAX6305UK00D1 is a CMOS microprocessor supervisory circuit designed to monitor multiple power supplies. It features two adjustable undervoltage inputs and operates within a supply voltage range up to 5.5V. The device provides an active low, open-drain reset output with a typical delay of 1.4ms. It draws 8µA of supply current and is housed in a compact SOT-23-5 package.

Supervisors Feature Summary

• Monitors multiple power rails using two programmable input channels
• Provides system reset assertion when monitored voltages fall below thresholds
• Designed to ignore fast transients on monitored supplies

Supervisors Applications

• Personal computer systems monitoring 5V and 3.3V supplies
• Portable applications requiring low supply current
• Multi-supply microprocessor supervision

Supervisors Procurement Notes

Verify the specific suffix (e.g., D1 vs D2) against the manufacturer datasheet to confirm pinout and threshold configurations. Ensure RoHS compliance status matches project requirements. Confirm availability as distribution status may vary by region.

Supervisors Selection Notes

Select this component for designs requiring dual-input voltage supervision in a small footprint. The adjustable thresholds allow flexibility for various rail combinations. Consider the 8µA quiescent current for battery-powered applications.

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 more than one power supply in portable and desktop systems.

Supervisors Replacement Considerations

Check MAX6305UK00D2+T for similar functionality. Verify that the replacement maintains the same SOT-23-5 package and electrical characteristics before substitution.
