Overview
The BTS5662EAUMA1 is a six-channel LED driver IC manufactured by Infineon Technologies, designed for automotive applications. It integrates a DC-DC regulator with a switched capacitor (charge pump) topology to drive high-current loads. Each channel supports up to 24A output current. The device operates on a supply voltage range of 5.5V to 28V and features SPI-based dimming control. It is housed in a 36-BSSOP package with an exposed pad, suitable for surface mount installation, and functions within a junction temperature range of -40°C to 150°C.
Feature Summary
- Integrates a switched capacitor charge pump topology for efficient DC-DC regulation without external inductors.
- Provides six independent output channels capable of driving high-current LED loads.
- Supports digital control via Serial Peripheral Interface (SPI) for precise dimming and configuration.
Applications
- Automotive exterior lighting systems
- High-power LED headlamp modules
- Adaptive driving beam applications
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix 'AUMA1' matches the required package and tape-and-reel specifications. Check for obsolescence status as this part may be discontinued. Ensure ESD handling protocols are followed during storage and assembly due to moisture sensitivity level 3 classification.
Selection Notes
Select this component when designing multi-channel LED drivers requiring high current density per pin. The integrated charge pump simplifies PCB layout by eliminating bulky inductors. Verify that the system power supply remains within the 5.5V to 28V operating window. Consider thermal management requirements given the 24A per channel capability and the exposed pad package design for heat dissipation.
Part Context
This device belongs to Infineon's automotive-grade LED driver family. It is engineered for reliability in harsh environments, meeting stringent automotive standards. The integration of regulation and switching functions reduces the overall bill of materials compared to discrete solutions. It serves as a specialized solution for complex lighting architectures in modern vehicles.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Consult official Infineon resources for cross-reference data if this obsolete part requires replacement.
