MAX6306UK31D1+

Supervisors Overview

The MAX6306UK31D1+ is a CMOS microprocessor supervisory circuit designed to monitor multiple power supplies. It features a fixed reset threshold voltage of 3.1V and supports up to two monitored inputs. The device provides an active-low, open-drain output with a manual reset input capability. It operates within a supply voltage range of 2.5V to 5.5V and draws a typical quiescent current of 8µA. The component is housed in a compact SOT-23-5 surface-mount package.

Supervisors Feature Summary

• Monitors multiple power supply rails simultaneously for system integrity
• Includes a manual reset input for external control
• Provides active-low open-drain reset signal output
• Designed to ignore fast transients on monitored supplies

Supervisors Applications

• Personal computer systems monitoring 5V and 3.3V rails
• Portable electronic devices requiring low supply current
• Microprocessor supervisory circuits
• Battery-powered equipment

Supervisors Procurement Notes

Verify the specific suffix D1 against official Analog Devices documentation to confirm the exact factory-programmed threshold voltage and tolerance. Ensure the ordering part number matches the required pinout and package type. Confirm RoHS compliance status through the manufacturer's latest datasheet or certification documents before procurement.

Supervisors Selection Notes

Select this component when simultaneous monitoring of multiple voltage rails is required. The fixed 3.1V threshold suits applications where this specific level triggers the reset condition. Consider the 8µA quiescent current for battery life optimization. Verify that the SOT-23-5 package fits the PCB layout constraints.

Supervisors Part Context

This part belongs to the MAX6305–MAX6313 family of 5-pin, multiple-input, programmable reset ICs from Maxim Integrated. These devices are engineered to assert a system reset if any monitored supply falls outside its programmed threshold. The series is characterized by low supply current and small package size, making it suitable for portable applications.

Supervisors Replacement Considerations

Check the MAX6306UK31D1+ datasheet for officially listed equivalent parts or direct replacements within the MAX6305–MAX6313 family. Ensure any substitute maintains the same 3.1V threshold, SOT-23-5 package, and dual-input monitoring capability.
