MAX6312EUK46D3+

Supervisors Overview

The MAX6312EUK46D3+T is a CMOS microprocessor supervisory circuit designed to monitor multiple power supplies. It features a factory-programmed reset threshold voltage of 4.63V 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 includes a manual reset input and consumes only 15µA of supply current. Packaged in a compact SOT-23-5 format, it supports operation from -40°C to +85°C.

Supervisors Feature Summary

• Monitors multiple power supplies and asserts reset if any fall outside programmed thresholds
• Features a manual reset input for system control
• Designed to ignore fast transients on monitored supplies

Supervisors Applications

• Monitoring 5V and 3.3V supplies in personal computer systems
• Portable applications requiring low supply current
• Microprocessor supervisory circuits

Supervisors Procurement Notes

Verify the specific suffix D3 indicates tape-and-reel packaging when ordering. Confirm the 4.63V threshold matches design requirements. Check availability status as distribution may vary. Ensure compatibility with SOT-23-5 footprint during PCB layout.

Supervisors Selection Notes

Select this component for multi-supervision tasks where precise threshold monitoring is required. The fixed 4.63V threshold suits specific rail monitoring needs. Consider the low quiescent current for battery-operated designs. Verify package constraints against board space limitations.

Supervisors Part Context

Part of the MAX6305–MAX6313 family of 5-pin, multiple-input programmable reset ICs. These devices are optimized for portable applications due to low power consumption and small package size. They provide reliable supervision for complex power architectures.

Supervisors Replacement Considerations

Other members of the MAX6305–MAX6313 series offer different threshold voltages. Verify that alternative part numbers match the required reset threshold and package type before substitution.
