MAX6307UK31D3+T

Supervisors Overview

The MAX6307UK31D3+T is a supervisory circuit designed for monitoring multiple power supplies. It features two monitored inputs with fixed reset thresholds of 3.3 V and 5 V. The device operates within a supply voltage range up to 5.5 V and draws an operating current of 8 µA. It provides an active low, open-drain output with a manual reset input capability. The reset delay time is specified at 200 ms. Operating temperatures range from 0°C to +70°C. The component is housed in a SOT-23-5 surface-mount package.

Supervisors Feature Summary

• Monitors two distinct power supply rails simultaneously
• Includes a manual reset input for system control
• Features low quiescent current consumption suitable for portable applications
• Provides active low open-drain reset output

Supervisors Applications

• Personal computer systems requiring dual voltage supervision
• Portable electronic devices needing low-power monitoring
• Embedded systems managing 3.3V and 5V logic levels

Supervisors Procurement Notes

Verify the specific suffix D3 against official Analog Devices documentation to confirm the exact threshold configuration and package variant. Confirm RoHS compliance status through the manufacturer's latest certification records. Ensure the sourcing channel provides valid traceability for this discontinued or limited-supply component.

Supervisors Selection Notes

Select this component when simultaneous monitoring of 3.3V and 5V rails is required without adjustable thresholds. Consider the 200ms reset delay and open-drain output characteristics for interface compatibility. Evaluate the 0°C to +70°C temperature range against environmental requirements before implementation.

Supervisors Part Context

This part belongs to the MAX6305–MAX6313 series of CMOS microprocessor supervisory circuits. These devices are engineered to ignore fast transients on monitored supplies. The series offers factory-programmed thresholds and is optimized for applications requiring reliable reset generation under varying power conditions.

Supervisors Replacement Considerations

Consult the official datasheet for direct pin-compatible alternatives within the MAX6307 family. Verify that substitute parts maintain identical threshold voltages and output configurations.
