MAX16039LLA29+T

Supervisors Overview

The MAX16039LLA29+T is a low-power voltage supervisory circuit designed for battery-backup applications. It features a 2.93 V threshold voltage and an active-low, open-drain output. The device operates within a supply voltage range up to 5.5 V and consumes 22 uA of quiescent current. It provides a reset delay time of 280 ms and includes overvoltage protection with a 3 V threshold. The component is housed in an 8-lead UDFN package and functions across a temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Integrates battery backup switching functionality for seamless power source transitions.
• Provides hardware-based overvoltage detection to protect downstream components.
• Delivers a reliable reset signal via an active-low open-drain output pin.

Supervisors Applications

• Low-power battery-backed systems requiring voltage supervision
• Portable electronic devices with limited power budgets
• Embedded systems needing overvoltage protection

Supervisors Procurement Notes

Verify the specific suffix LLA29 to confirm the exact threshold voltage and package variant. Confirm RoHS compliance status through official documentation. Check for obsolescence notices or lifecycle changes directly from Analog Devices. Ensure the ordering part number matches the required electrical specifications exactly before procurement.

Supervisors Selection Notes

Select this component when a dedicated battery backup switch and overvoltage monitor are required in a small footprint. Consider the 22 uA quiescent current for battery life calculations. Verify that the 2.93 V threshold aligns with the system's minimum operating voltage requirements. Ensure the UDFN-8 package fits the available PCB space constraints.

Supervisors Part Context

This part belongs to the MAX16039 series of supervisory circuits from Maxim Integrated. These devices are engineered for compact designs where power efficiency and voltage monitoring are critical. The series typically offers various threshold options and package styles to suit different application needs.

Supervisors Replacement Considerations

Consult Analog Devices documentation for direct cross-references. Verify compatibility of threshold voltages and package dimensions. Ensure functional equivalence for battery backup and overvoltage protection features before substitution.
