MAX16037LLA31+

Supervisors Overview

The MAX16037LLA31+ is an EEPROM-based system monitor manufactured by Analog Devices Inc./Maxim Integrated. It features a fixed threshold voltage of 3.08V and supports eight monitored inputs. The device utilizes a TQFN-48 EP package with surface mount installation. It operates within a supply voltage range up to 14V and maintains an accuracy of 1%. The component functions within a temperature range of -40°C to +85°C, drawing a typical operating current of 3mA.

Supervisors Feature Summary

• EEPROM-based configuration storage for nonvolatile parameter retention
• Eight-input voltage monitoring capability with adjustable thresholds
• Manual reset functionality with active low open-drain output

Supervisors Applications

• Multi-rail power supply supervision in industrial systems
• Embedded controller monitoring in telecommunications equipment
• System integrity verification in automotive electronics

Supervisors Procurement Notes

Verify the specific suffix LL A31 against official datasheets to confirm the fixed 3.08V threshold and package type. Confirm RoHS compliance status through manufacturer documentation. Check for obsolescence notices or limited availability indicators directly from Analog Devices. Ensure the ordering part number matches the required pinout and thermal pad specifications for the TQFN-48 EP package.

Supervisors Selection Notes

Select this component when fixed voltage supervision at approximately 3.08V is required without external resistor dividers. The integrated EEPROM allows for field-programmable parameters, reducing bill-of-materials complexity. Consider the TQFN-48 EP package for thermal performance and space-constrained designs requiring multiple monitored rails.

Supervisors Part Context

This part belongs to the MAX16031/MAX16037 family of EEPROM-based system monitors. These devices are designed for applications requiring reliable supervision of multiple voltage rails with persistent configuration settings. The family distinguishes itself through nonvolatile memory integration, allowing customization of reset thresholds and timing parameters without external components.

Supervisors Replacement Considerations

Consult official cross-reference lists for direct replacements. Verify that any substitute maintains the 3.08V threshold, 8-channel monitoring capacity, and TQFN-48 EP footprint. Ensure compatibility with existing EEPROM programming interfaces and reset logic requirements.
