MAX16039LLA31+

Supervisors Overview

The MAX16039LLA31+ is a low-power voltage supervisory circuit designed for battery-backup applications. It features an active-low, open-drain output and operates within a supply voltage range of up to 5.5 V. The device monitors a single input with a threshold voltage of 3.08 V and provides a reset delay time of 280 ms. It draws a typical operating supply current of 8 µA and functions reliably across an industrial temperature range from -40°C to +85°C. The component is housed in an 8-µDFN (2x2) package.

Supervisors Feature Summary

• Integrated battery backup switch functionality for seamless power source management
• Ultra-low quiescent current consumption suitable for energy-constrained designs
• Compact surface-mount packaging optimized for space-limited PCB layouts

Supervisors Applications

• Portable electronic devices requiring efficient power monitoring
• Battery-operated systems needing reliable voltage supervision
• Embedded controllers utilizing backup power sources

Supervisors Procurement Notes

Verify the specific suffix designation to ensure correct threshold voltage and package configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Check for obsolescence notices or lifecycle changes directly from Analog Devices to mitigate supply chain risks during long-term production planning.

Supervisors Selection Notes

Select this component when a dedicated battery backup switch is required alongside voltage supervision. Ensure the 3.08 V threshold aligns with the system's minimum operating voltage requirements. Consider the 8 µA current draw against total system power budgets. Verify that the open-drain output interface is compatible with the target microcontroller or logic family inputs.

Supervisors Part Context

This part belongs to the MAX16039 series of low-power supervisory circuits from Maxim Integrated. The series is characterized by minimal current consumption and small footprint options. It targets applications where power efficiency and physical size are critical constraints, distinguishing it from higher-current general-purpose supervisors.

Supervisors Replacement Considerations

Consult official cross-reference data for verified substitutes. Generic equivalents may lack the specific battery backup switch feature or exact threshold accuracy.
