Procurement Notes

Verify the specific suffix 'B' against official Analog Devices documentation to confirm exact electrical tolerances and revision status. Confirm AEC-Q100 qualification requirements match your target automotive application standards. Check current availability status as distribution channels may indicate limited stock or restricted supply conditions for this specific part number variant.

Selection Notes

Select this component when designing power architectures for automotive TFT-LCD panels requiring high input voltage tolerance up to 36V. Ensure the 28-TSSOP-EP thermal pad footprint aligns with PCB layout capabilities. Validate that the 2.2MHz switching frequency fits EMI constraints for the specific vehicle environment compared to lower-frequency alternatives.

Part Context

This part belongs to the MAX16929 series of automotive LCD drivers from Maxim Integrated, now part of Analog Devices. It shares functional similarities with variants like MAX16929CGUI/V+ and MAX16929AGUI/V+T, differing primarily in manufacturing revisions or specific binning parameters defined by the manufacturer's internal coding.

Replacement Considerations
