Procurement Notes

Verify component authenticity through authorized channels due to limited availability status. Confirm the specific suffix matches the required package and qualification standards. Check for obsolescence notices as this part may be subject to restricted supply or end-of-life conditions. Ensure compatibility with existing design specifications before procurement.

Selection Notes

Select this component when adjustable overvoltage thresholds are required alongside high-temperature operation capabilities. Consider the 150 ms reset delay and low supply current for power-sensitive applications. Verify that the TQFN-12 package fits the PCB layout constraints. Ensure the 30 V maximum supply rating aligns with the system's peak voltage requirements.

Part Context

This part belongs to the MAX16126 series of supervisory circuits focused on automotive-grade protection. It shares functional similarities with other models in the family but offers specific threshold adjustments and packaging options. The series is designed to meet rigorous automotive reliability standards, including AEC-Q100 qualification for durability in demanding electrical environments.

Replacement Considerations

Public confirmed substitute part numbers include MAX16126TCA/V+, MAX16126TCD/V+, and MAX16126TCB/V+. These alternatives share similar protection functions and package types but may differ in specific threshold settings or manufacturing lot details. Verify pinout and electrical parameters before substitution.
