Procurement Notes

Verify component authenticity through authorized channels due to potential availability constraints. Confirm the specific suffix matches the required package and temperature grade. Check for end-of-life status or obsolescence notices from Analog Devices before finalizing procurement plans. Ensure compliance with RoHS3 standards as indicated in official documentation.

Selection Notes

Select this component when adjustable overvoltage thresholds are required for load dump scenarios. Consider the 260µA quiescent current for low-power design constraints. Verify that the 8-uMAX package dimensions fit the target PCB layout. Ensure the input voltage range covers the maximum expected system voltage without exceeding the 30V limit.

Part Context

This part belongs to the MAX16129 series of supervisory circuits focused on power management protection.
