BTS5672EAUMA2

Overview

The BTS5672EAUMA2 is a six-channel LED driver IC from Infineon Technologies, designed for automotive applications. It integrates a DC-DC switching capacitor (charge pump) topology with internal switches to regulate current up to 24A per channel. The device operates on an SPI interface for dimming and control, supporting a supply voltage range of 5.5V to 28V. It functions at a frequency of 2MHz and is housed in a 36-BSSOP package with exposed pads, rated for junction temperatures between -40°C and 150°C.

Feature Summary

• Integrates six independent high-current output channels regulated by an internal charge pump topology
• Supports digital control and dimming via Serial Peripheral Interface (SPI)
• Includes internal power switches eliminating the need for external components
• Engineered for automotive-grade reliability with extended thermal operating ranges

Applications

• Automotive exterior lighting systems
• Advanced headlight modules requiring precise current regulation
• LED illumination circuits in vehicle interior ambient lighting
• High-power LED arrays in automotive signaling applications

Procurement Notes

Verify the specific suffix EAUMA2 against official Infineon documentation to confirm pinout and electrical specifications. Ensure compatibility with automotive environmental standards before integration. Confirm availability status as product lifecycles may change. Cross-reference datasheet revisions to validate parameter consistency for your specific design requirements.

Selection Notes

Select this component when designing automotive LED systems requiring high current density per channel. The integrated charge pump simplifies board layout by reducing external passive components. Verify that the SPI interface aligns with the host microcontroller's communication capabilities. Ensure the thermal management solution supports the specified junction temperature limits under maximum load conditions.

Part Context

This part belongs to the BTS5672 family of smart power switches developed for automotive lighting control. It represents a second-generation solution offering enhanced power density and digital controllability compared to earlier analog or lower-integration counterparts. The series is tailored for modern vehicle architectures demanding efficient, compact, and reliable LED driving solutions.

Replacement Considerations

Check for direct substitutes within the BTS56xx series such as the BTS5682E variants. Verify pin-to-pin compatibility and identical electrical characteristics before substitution. Consult Infineon's official obsolescence notices for lifecycle updates.
