MAX16033LLB31+T

Supervisors Overview

The MAX16033LLB31+T is a low-power supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of 0V to 5.5V and features an adjustable threshold voltage of 3.1V. The device monitors a single input channel and provides an active-low, open-drain output. It includes manual reset functionality and battery backup support. The component is housed in a compact UDFN-10 package, suitable for surface mount installation. It supports a reset delay time of 280ms and maintains operation across a temperature range of -40°C to +85°C with a quiescent current of 22µA.

Supervisors Feature Summary

• Integrates battery backup switching capability for continuous system monitoring during power transitions.
• Provides precise voltage supervision with adjustable threshold detection for flexible system configuration.
• Delivers active-low open-drain reset signaling compatible with standard digital logic interfaces.

Supervisors Applications

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

Supervisors Procurement Notes

Verify the specific suffix LLB31+T against official datasheets to confirm the exact threshold voltage and package variant. Confirm availability status as distribution channels may list obsolete or limited stock items. Ensure compatibility with existing PCB footprints for the UDFN-10 package before procurement.

Supervisors Selection Notes

Select this component when a single-channel supervisor with battery backup is required. The adjustable threshold allows customization for various rail voltages. Consider the low quiescent current for battery life optimization. Verify that the UDFN-10 package fits the design constraints compared to other family members.

Supervisors Part Context

This part belongs to the MAX16033-MAX16040 series of low-power supervisory circuits. These devices are designed to monitor system voltages and provide reset signals. The series emphasizes small package sizes and low power consumption, making them suitable for space-constrained applications.

Supervisors Replacement Considerations

Check for pin-compatible alternatives within the MAX1603x series with different fixed thresholds if adjustment is not needed. Verify thermal performance and package dimensions against potential substitutes from other manufacturers offering similar single-channel supervision.
