Procurement Notes
Verify component obsolescence status before integration into new designs. Confirm availability through authorized distributors or secondary market suppliers. Ensure compatibility with existing PCB footprints and thermal requirements. Review latest datasheet revisions for any pinout or electrical specification updates prior to procurement.
Selection Notes
Select this component for applications requiring high-current LED regulation with digital control capabilities. Consider the 36-pin package size and thermal dissipation needs when designing the layout. Evaluate the SPI interface compatibility with the host microcontroller. Assess the charge pump efficiency against system power constraints.
Part Context
This part belongs to Infineon's LED driver family, specifically utilizing charge pump technology for high-side switching. It differs from linear drivers by offering higher efficiency in step-up configurations. The BTS5572EAUMA1 represents a specialized solution for multi-channel LED strings where voltage headroom is limited.
Replacement Considerations
Public confirmed substitute part numbers are not available due to the component's obsolete status. Designers should evaluate newer generations from the same manufacturer or equivalent functional alternatives that support SPI dimming and similar current ratings.
