Procurement Notes
Verify the exact part number suffix carefully, as variations such as QDCARQ1 or AQDCARQ1 exist within the same family. Confirm availability status, as some variants are marked as Not Recommended for New Designs (NRND). Ensure compliance with RoHS directives and moisture sensitivity levels before integration into production schedules.
Selection Notes
Select this component when designing power architectures for TI safety-grade microcontrollers requiring integrated rail management. Consider the specific output current capabilities and thermal performance relative to the HTSSOP-48 package constraints. Evaluate compatibility with the target microcontroller's power-up sequencing requirements.
Part Context
This part is part of the TPS65385x-Q1 family of multirail power supplies. It serves as a dedicated power management solution for complex automotive microcontroller units, consolidating multiple voltage rails into a single compact package to reduce board space and simplify design.
Replacement Considerations
Check for TPS653850AQDCARQ1 or TPS653852AQDCARQ1 if different output configurations are needed. Verify functional equivalence with TPS653853AQDCARQ1 for direct pin-to-pin substitution.
