MAX16035PLB31+T

Supervisors Overview

The MAX16035PLB31+T is a low-power battery backup supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 0 V to 5.5 V and features a fixed undervoltage threshold of 3.08 V. The device monitors a single input line and provides an open-drain or open-collector reset output. It is housed in a compact 10-µDFN (2x2 mm) package, suitable for space-constrained designs. The component draws a typical operating current of 22 µA and functions reliably across an industrial temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Provides continuous monitoring of battery backup voltage levels with a fixed threshold
• Delivers a reset signal via an open-drain or open-collector output interface
• Designed for ultra-low power consumption in portable applications
• Utilizes a small footprint surface-mount package for dense PCB layouts

Supervisors Applications

• Battery-powered portable electronic devices requiring voltage supervision
• Embedded systems utilizing external battery backup sources
• Consumer electronics with limited power budgets
• Industrial control modules needing reliable power-fail detection

Supervisors Procurement Notes

Verify the specific suffix code to confirm the exact undervoltage threshold, as the MAX16035 series offers multiple voltage options. Confirm the package type matches the design requirements, typically 10-UDFN. Check for end-of-life status or obsolescence notices from the manufacturer before finalizing procurement plans. Ensure compatibility with the target system's logic levels for the reset output.

Supervisors Selection Notes

Select this component when a fixed 3.08 V threshold is required for battery backup monitoring. Consider the 22 µA quiescent current if power efficiency is critical. The open-drain output requires an external pull-up resistor; ensure the resistor value aligns with the system's speed and voltage requirements. Verify that the 10-µDFN package dimensions fit within the available board space constraints.

Supervisors Part Context

This part belongs to the MAX16035 family of low-power battery backup circuits. The series includes various variants differentiated by their undervoltage threshold voltages, indicated by the suffix codes. These components are designed to replace older supervisor ICs while offering improved power efficiency and smaller form factors. The family is widely used in applications where maintaining data integrity during power transitions is essential.

Supervisors Replacement Considerations

Direct substitutes include other MAX16035 variants with different threshold voltages, such as MAX16035PLB31+T equivalents if voltage tolerance allows. Cross-reference with MAX16035PLBxx+T series parts for pin-compatible alternatives. Verify that any replacement maintains the same 10-UDFN package and electrical characteristics.
