MAX16033PLB31+T

Supervisors Overview

The MAX16033PLB31+T is a low-power supervisory circuit designed for battery-backup applications. It operates within a supply voltage range of 0V to 5.5V and features an active-low, open-drain reset output. The device provides a fixed reset delay of 280 ms and monitors the supply voltage against a threshold of 3.08V. Packaged in a compact 10-µDFN (2x2 mm) form factor, it minimizes component count and board space while ensuring reliable system monitoring.

Supervisors Feature Summary

• Active-low open-drain reset output for direct interface with microprocessors
• Fixed 280 ms reset delay ensures stable power-up sequencing
• Compact 10-µDFN package reduces footprint requirements

Supervisors Applications

• Battery backup systems requiring voltage supervision
• Microprocessor reset circuits in embedded devices
• Portable electronics with limited board space

Supervisors Procurement Notes

Verify the exact suffix PLB31+T corresponds to the 3.08V threshold and 280ms delay specifications. Confirm RoHS compliance status through official Analog Devices documentation. Ensure the UDFN-10 package matches your PCB layout requirements before procurement.

Supervisors Selection Notes

Select this part when a fixed 3.08V threshold and 280ms delay are required. The open-drain output allows flexibility in pull-up voltage selection. Consider the 10-µDFN package size for space-constrained designs. Verify input voltage range compatibility with your system's 0V-5.5V operation.

Supervisors Part Context

Part of the MAX16033–MAX16040 series of low-power battery-backup supervisory circuits. These devices simplify design by reducing external components. The MAX16033 variant specifically offers fixed thresholds and delays for standard applications.

Supervisors Replacement Considerations

Check MAX16033LLB29+ for alternative threshold/delay combinations within the same series. Verify pinout and package compatibility before substitution.
