MAX16042TP+T

Supervisors Overview

The MAX16042TP+T is a supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated, designed for multi-voltage system monitoring. It features three independent voltage monitor channels housed in a 20-TQFN package with an exposed pad. The device operates within a supply voltage range of 2.7 V to 5.5 V and supports a threshold voltage of 3.1 V. It provides active-low or active-high push-pull outputs and includes manual reset functionality. The component ensures reliable power management with a reset delay time of 215 ms and operates across a temperature range of -40°C to +125°C.

Supervisors Feature Summary

• Integrates three independent voltage monitor channels for simultaneous multi-rail supervision
• Provides configurable active-low or active-high push-pull output states
• Includes manual reset input capability for system control flexibility
• Features robust ESD protection and high immunity to noise transients

Supervisors Applications

• Multi-voltage embedded systems requiring simultaneous power rail supervision
• Industrial control units with complex power distribution networks
• Communication equipment needing reliable brown-out detection
• Portable devices utilizing multiple battery or supply sources

Supervisors Procurement Notes

Verify the specific suffix 'TP' against the official datasheet to confirm pinout and package dimensions, as variations exist within the MAX16042 family. Ensure the '+T' designation matches the required reel quantity for your manufacturing process. Cross-reference the manufacturer part number with the latest Analog Devices documentation to confirm current production status and any potential obsolescence notices before finalizing procurement plans.

Supervisors Selection Notes

Select this component when three distinct voltage rails require independent monitoring within a single footprint. The 20-TQFN package offers thermal advantages via the exposed pad for high-temperature applications up to 125°C. Consider the manual reset feature if external system control over the reset state is necessary. Verify that the 3.1 V threshold aligns with the lowest monitored rail's minimum operating voltage to ensure proper trigger timing.

Supervisors Part Context

The MAX16042 belongs to the Maxim Integrated supervisory circuit portfolio, focusing on power management integrity. Unlike single-channel monitors, this triple-channel variant simplifies board space by consolidating multiple supervision functions. It complements other PMIC solutions by providing precise voltage tracking without requiring external resistors for threshold setting in standard configurations.

Supervisors Replacement Considerations

Check for MAX16042 variants with different suffixes (e.g., LLA, PLA) which may offer alternative thresholds or packages. Verify compatibility with MAX16044 or MAX16046 if additional channels are needed, noting pinout differences.
