MAX16037LLA26+T

Supervisors Overview

The MAX16037LLA26+T is a low-power voltage supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of 1.6 V to 5.5 V and features a fixed under-voltage threshold of 2.625 V with an over-voltage threshold of 2.678 V. The device provides an active-low, open-drain reset output with a typical delay of 280 ms. It consumes only 22 µA of quiescent current and includes a battery backup switch for seamless transition between power sources. The component is housed in an 8-pin UDFN package and supports operation from -40°C to +85°C.

Supervisors Feature Summary

• Integrates a battery backup switch to maintain system state during power transitions
• Provides precise monitoring of single input voltage lines via fixed thresholds
• Delivers an active-low open-drain reset signal with configurable delay characteristics

Supervisors Applications

• Portable electronic devices requiring low-power voltage supervision
• Battery-operated systems needing backup power management
• Embedded controllers requiring reliable reset generation

Supervisors Procurement Notes

Verify the specific suffix LLA26 against official datasheets to confirm the exact threshold voltage and package variant. Confirm RoHS compliance status through manufacturer documentation. Check for obsolescence notices or limited availability directly from Analog Devices distributors before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a single-channel supervisor with integrated battery backup is required. Ensure the 2.625 V threshold aligns with the target rail voltage. Verify that the UDFN-8 package fits the PCB layout constraints. Compare quiescent current specifications against other options if ultra-low power consumption is critical.

Supervisors Part Context

This part belongs to the MAX16037 series of voltage supervisors designed for space-constrained applications. The series emphasizes low power consumption and compact packaging solutions suitable for modern portable electronics. It complements broader power management portfolios by offering dedicated reset functionality without external components.

Supervisors Replacement Considerations

Consult official cross-reference guides for direct replacements. Verify pin compatibility and electrical parameters such as threshold voltages and quiescent current before substituting.
