MAX6464UK31+T

Supervisors Overview

The MAX6464UK31+T is a single-channel ultra-low-power voltage monitor from the MAX6464 family, manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of up to 6 V and features a fixed threshold voltage of 3.2 V with an accuracy of 2.5%. The device provides an active low, push-pull output and includes a reset delay time of 260 ms. It functions in temperatures from -40°C to +125°C, consumes 3.5 µA of operating current, and is housed in an SC-70-3 package.

Supervisors Feature Summary

• Monitors system voltages using a precision bandgap reference and comparator
• Provides reliable circuit protection through internal threshold hysteresis
• Eliminates external components for nominal voltage monitoring applications

Supervisors Applications

• Battery-powered portable electronics
• Microprocessor power-supply supervision
• System voltage monitoring in industrial equipment

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm RoHS compliance status and check for obsolescence notices. Ensure the specific suffix matches required packaging and temperature grades. Validate datasheet revisions against design requirements before procurement.

Supervisors Selection Notes

Select this part for applications requiring a fixed 3.2 V threshold with push-pull output capability. Consider the 260 ms reset timeout and 3.5 µA quiescent current for low-power designs. Verify that the SC-70-3 package fits the board layout constraints and thermal requirements.

Supervisors Part Context

This component belongs to the MAX6461–MAX6466 family of ultra-low-power voltage detectors and microprocessor supervisory circuits. The series offers various thresholds from 1.6 V to 5.5 V in 100 mV increments. The MAX6464 variant specifically provides a minimum reset timeout period of 150 ms, distinguishing it from faster voltage detectors in the same family.

Supervisors Replacement Considerations

Check for direct pin-compatible substitutes within the MAX6464 series with different threshold voltages. Verify if alternative packages like SOT-23-5 are available for the same electrical specifications.
