MAX16040LLA46+T

Supervisors Overview

The MAX16040LLA46+T is a single-channel voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. Designed for battery backup applications, it monitors system power integrity within a UDFN-10 package. The device operates with a maximum supply voltage of 5.5 V and features an undervoltage threshold of 4.5 V alongside an overvoltage threshold of 4.75 V. It functions effectively across a temperature range from -40°C to +85°C while consuming only 22 µA of quiescent current.

Supervisors Feature Summary

• Provides dedicated monitoring for battery backup systems to ensure data retention during power transitions.
• Integrates both undervoltage and overvoltage detection capabilities within a single channel.
• Operates with minimal power consumption suitable for energy-efficient embedded designs.

Supervisors Applications

• Battery backup power monitoring circuits
• Embedded system voltage supervision
• Data retention protection in portable electronics

Supervisors Procurement Notes

Verify component authenticity through authorized distributors due to limited availability status. Confirm package integrity and RoHS compliance upon receipt. Cross-reference datasheet specifications against design requirements before integration. Check for obsolescence notices or lifecycle changes from the manufacturer. Ensure storage conditions meet semiconductor handling standards.

Supervisors Selection Notes

Evaluate the specific voltage thresholds against the target system's nominal operating levels. Consider the UDFN-10 footprint constraints for PCB layout optimization. Assess thermal performance requirements within the specified operating temperature range. Compare quiescent current consumption against other available supervisory options.
