MAX16127TC/V+T

Overview

The MAX16127TC/V+T is an automotive-grade supervisory circuit designed for load-dump and reverse-voltage protection. It operates within a supply voltage range of 3V to 30V and features an adjustable reset threshold voltage with a nominal minimum of 1.2V. The device provides an active-low, open-drain output and includes a fixed reset delay time of 150 ms. It supports limiter-mode fault management for overvoltage and thermal shutdown conditions. Packaged in a 12-TQFN (3x3) surface-mount case, it functions reliably across an operating temperature range of -40°C to 125°C (TA).

Feature Summary

• Provides dedicated load-dump and reverse-voltage protection for automotive systems.
• Features limiter-mode fault management for handling overvoltage and thermal shutdown events.
• Offers adjustable reset threshold voltage with an active-low, open-drain output configuration.

Applications

• Automotive load dump protection circuits
• Reverse voltage protection systems
• Overvoltage fault management applications

Procurement Notes

Verify component authenticity through authorized Analog Devices channels due to limited supply status reported by some distributors. Confirm AEC-Q100 qualification and RoHS compliance against the latest datasheet revision. Ensure the specific TC/V suffix matches design requirements for package and temperature grade before finalizing procurement orders.

Selection Notes

Select this component when limiter-mode fault management is required rather than switch-mode operation found in related models like the MAX16126. Ensure the input voltage stays within the 3V to 30V range. Verify that the 150 ms reset delay aligns with system timing constraints. The 12-TQFN package requires appropriate PCB footprint design for thermal dissipation.

Part Context

This part belongs to the MAX16126/MAX16127 family of supervisory circuits from Maxim Integrated, now part of Analog Devices. While the MAX16126 utilizes switch-mode fault management, the MAX16127 specifically employs limiter-mode control. Both share similar packaging and electrical characteristics but differ in their approach to managing fault conditions in automotive power environments.

Replacement Considerations

The MAX16126TC/V+T is a related variant within the same family but differs in fault management mode (switch-mode vs. limiter-mode). Direct substitution requires verifying if the system architecture supports switch-mode operation instead of the limiter-mode provided by the MAX16127. No other direct cross-references are confirmed in public documentation.
