MAX16039LLA23+T

Supervisors Overview

The MAX16039LLA23+T is a low-power battery backup circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1V to 5.5V and features a threshold voltage of 2.3V. The device provides an active-low, open-drain output with a reset delay time of 280 ms. It consumes only 22 µA of operating current and functions reliably across a temperature range of -40°C to +85°C. Packaged in an 8-µDFN (2x2) format, it is designed for compact electronic applications requiring efficient power monitoring.

Supervisors Feature Summary

• Integrated battery backup functionality for continuous system monitoring
• Ultra-low power consumption suitable for battery-operated devices
• Compact surface-mount package design for space-constrained layouts

Supervisors Applications

• Portable consumer electronics
• Battery-powered instrumentation
• Embedded systems requiring voltage supervision

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific lot traceability requirements prior to acquisition. Ensure storage conditions align with moisture sensitivity level specifications to maintain device integrity during assembly processes.

Supervisors Selection Notes

Select this component when a dedicated battery backup supervisor is required alongside standard voltage monitoring. Compare the 2.3V threshold against system brownout limits. Evaluate the 280 ms reset delay against processor startup times. Consider the 8-µDFN footprint compatibility with existing PCB silkscreens and copper pad designs.

Supervisors Part Context

This part belongs to the MAX16039 series of supervisory circuits. It shares architectural similarities with variants like the MAX16039LLA29+T but differs in threshold voltage settings. The series targets applications needing reliable power management in minimal footprints without external components.

Supervisors Replacement Considerations

The MAX16039LLA29+T serves as a functional substitute with identical packaging and interface characteristics, differing primarily in its 2.93V threshold voltage specification.
