MAX16040LLA31+

Supervisors Overview

The MAX16040LLA31+ is a single-channel voltage supervisor manufactured by Analog Devices Inc./Maxim Integrated. It monitors one input voltage and provides a reset signal when the supply drops below or exceeds specific thresholds. The device features an adjustable threshold voltage of 3.1V, ensuring precise supervision for critical power rails. It operates within a supply voltage range of 2.2V to 28V and includes a manual reset input for system control. The component supports both open-drain and push-pull output configurations, offering flexibility in interface design. It is housed in an 8-µDFN package suitable for surface-mount applications.

Supervisors Feature Summary

• Provides reliable voltage monitoring with adjustable threshold detection capabilities
• Supports flexible output drive options including open-drain and push-pull configurations
• Includes manual reset functionality for controlled system initialization

Supervisors Applications

• Portable equipment requiring low-power voltage supervision
• Battery-powered systems needing under-voltage protection
• Embedded controllers requiring manual reset inputs

Supervisors Procurement Notes

Verify the exact suffix 'LLA31+' to confirm the 3.1V threshold specification. Ensure compatibility with the required output configuration (open-drain vs. push-pull) as defined by the datasheet. Confirm package availability in 8-µDFN format. Check for any recent product change notices regarding manufacturing updates.

Supervisors Selection Notes

Select this component when a single-channel supervisor with adjustable thresholds is required. Consider the 2.2V to 28V operating range for broad supply compatibility. Evaluate the need for manual reset functionality versus automatic-only operation. Compare power consumption requirements against the typical quiescent current specifications provided in the official documentation.

Supervisors Part Context

This part belongs to the MAX16040 series of voltage supervisors designed for portable and battery-operated applications. It offers a compact footprint with high accuracy and low power consumption. The series is known for providing essential power management functions in space-constrained designs.

Supervisors Replacement Considerations

Consult the official datasheet for direct pin-to-pin replacements within the MAX16040 family. Verify that alternative parts match the 3.1V threshold and output type requirements.
