MAX6305UK00D1+T

Supervisors Overview

The MAX6305UK00D1+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 an active low, open-drain reset output. The device monitors two inputs with thresholds of 3.3V and 5V. It includes a fixed reset delay time of 1.4ms and draws a typical operating supply current of 8µA. Packaged in a compact SOT-23-5 format, it supports surface mount installation.

Supervisors Feature Summary

• Monitors multiple power supply rails simultaneously
• Asserts system reset when monitored voltages fall outside programmed 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
• Microprocessor supervisory circuits

Supervisors Procurement Notes

Verify the specific suffix D1 against official Analog Devices documentation to confirm exact threshold configurations. Cross-reference the manufacturer part number with authorized distributors to ensure authenticity. Confirm RoHS compliance status through the latest datasheet revision. Check for obsolescence or limited availability notices from the manufacturer before finalizing procurement plans.

Supervisors Selection Notes

Select this component when simultaneous monitoring of two distinct voltage rails is required. Ensure the 3.3V and 5V thresholds align with the target system's power architecture. Consider the 8µA quiescent current for battery-operated designs. Verify that the SOT-23-5 package dimensions fit the PCB layout constraints.

Supervisors Part Context

This part belongs to the MAX6305–MAX6313 series of 5-pin, multiple-input, programmable reset ICs manufactured by Maxim Integrated, now part of Analog Devices. These devices are specifically engineered for portable applications due to their small package size and low power consumption.

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.
