Overview
The TPS65471RHAR is a specialized power management integrated circuit (PMIC) manufactured by Texas Instruments. It is housed in an RHAR package and operates within a temperature range of -40°C to +85°C. The component is classified under professional power management ICs and is designed for surface mount installation. It serves as a dedicated power solution, integrating multiple power rails into a single compact device to simplify system design.
Feature Summary
- Integrates multiple power management functions into a single chip
- Designed for professional power management applications
- Supports surface mount technology for automated assembly
Applications
- OMAP35xx processor systems
- Professional embedded power solutions
- Complex system-on-chip power architectures
Procurement Notes
Verify the exact manufacturer part number against official Texas Instruments documentation to ensure compatibility with your specific board design. Confirm that the RHAR suffix matches your required package type and thermal characteristics. Check current availability status through authorized distributors, as supply levels may vary. Ensure that the operating temperature range meets your environmental requirements before finalizing procurement.
Selection Notes
Select this component when designing systems based on the OMAP35xx architecture or similar professional embedded platforms requiring integrated power management. Consider the VQFN-48 package constraints for PCB layout and thermal dissipation. Evaluate the total power budget and rail requirements against the PMIC's capabilities. Ensure that the +85°C maximum operating temperature aligns with your application's thermal profile.
Part Context
This PMIC belongs to the family of professional power management solutions from Texas Instruments, tailored for complex digital systems. It consolidates various voltage regulation needs, reducing component count and board space. The device is distinct from general-purpose regulators, offering optimized performance for specific processor families and industrial applications.
Replacement Considerations
Consult the official TPS6507x device comparison document for potential substitutes. Verify pin-to-pin compatibility and electrical parameter alignment with alternatives like the TPS650731 or TPS650732 before considering any cross-replacement.
