MAX6307UK27D3-T

Supervisors Overview

The MAX6307UK27D3-T is a CMOS microprocessor supervisory circuit designed to monitor multiple power supplies. It operates within a supply voltage range of 1V to 5.5V and features an active-low, open-drain reset output. The device monitors two inputs with a threshold voltage of 3.3V and 5V. It includes a reset delay time of 200ms and draws 8µA of operating supply current. The component is housed in a SOT-23-5 package.

Supervisors Feature Summary

• Monitors more than one power supply simultaneously
• Asserts system reset if monitored supplies fall outside programmed thresholds
• Designed to ignore fast transients on any monitored supply

Supervisors Applications

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

Supervisors Procurement Notes

Verify the specific suffix D3 against official Analog Devices documentation to confirm the exact threshold voltage configuration. Ensure the ordering part number matches the required reset threshold and package type for your design. Cross-reference the datasheet revision to confirm electrical characteristics before procurement.

Supervisors Selection Notes

Select this component when simultaneous monitoring of multiple voltage rails is required. The low supply current makes it suitable for battery-powered portable devices. Verify that the 200ms reset delay meets the timing requirements of the target microprocessor or logic circuit during power-up sequences.

Supervisors Part Context

This part belongs to the MAX6305–MAX6313 family of 5-pin, multiple-input, programmable reset ICs manufactured by Maxim Integrated, now part of Analog Devices. These devices are specifically engineered for microprocessor supervision in environments where transient immunity and multi-rail monitoring are critical.

Supervisors Replacement Considerations

Check for direct substitutes within the MAX6305–MAX6313 series that match the 3.3V/5V threshold configuration. Verify pinout compatibility and package dimensions (SOT-23-5) to ensure mechanical interchangeability without PCB redesign.
