MAX16039LLA31+T

Supervisors Overview

The MAX16039LLA31+T is a low-power voltage supervisory circuit manufactured by Analog Devices under the Maxim Integrated brand. It operates within a supply voltage range of up to 5.5 V and features a fixed threshold voltage of 3.125 V for monitoring power rails. The device provides an active-low, open-drain reset output with a typical reset delay time of 280 ms. Designed for battery backup applications, it includes a dedicated backup switch function to manage power source transitions. The component is housed in an 8-pin UDFN package and supports surface-mount installation. It functions as a single-input monitor without manual reset or watchdog timer capabilities, ensuring reliable system supervision across industrial temperature ranges.

Supervisors Procurement Notes

Verify component authenticity through authorized distributors. Confirm RoHS compliance status via official documentation. Ensure storage conditions meet manufacturer specifications to prevent moisture damage. Check for obsolescence notices before finalizing procurement plans.

Supervisors Selection Notes

Select this part when a fixed 3.125 V threshold is required. Consider the UDFN-8 package for space-constrained designs. Evaluate the 280 ms reset delay against system timing requirements. Verify compatibility with the target supply voltage range up to 5.5 V.

Supervisors Part Context

This component belongs to the MAX16039 series of low-power voltage supervisors. It shares functional similarities with other Maxim Integrated supervisory circuits but offers specific threshold and packaging options. The series targets applications demanding minimal power consumption and compact form factors.

Supervisors Replacement Considerations

Consult official cross-reference data for direct substitutes. Verify pinout compatibility and electrical parameter alignment before replacement.
