BTS5562EAUMA1

Overview

The BTS5562EAUMA1 is a five-channel high-side smart power switch manufactured by Infineon Technologies. It is housed in a PG-DSO-36 package and designed for automotive applications, holding AEC-Q100 qualification. The device integrates embedded protective functions to manage load connections efficiently. It operates within a supply voltage range of 5.5V to 28V and supports an output current of 24A per channel. The component features SPI dimming capability and functions as a DC-DC regulator using a switched capacitor topology. It is rated for junction temperatures between -40°C and 150°C.

Feature Summary

• Integrates five independent high-side switching channels with embedded diagnostic and protection mechanisms
• Supports digital control via Serial Peripheral Interface (SPI) for precise regulation and monitoring
• Utilizes a switched capacitor (charge pump) topology to function as a DC-DC LED driver
• Designed for robust automotive environments with extended temperature ratings

Applications

• Automotive exterior lighting systems requiring multi-channel regulation
• Interior ambient lighting configurations with digital control needs
• High-power LED arrays managed through SPI interfaces
• Smart power distribution units in vehicle electrical architectures

Procurement Notes

Verify the specific suffix EAUMA1 against official Infineon documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with existing SPI communication protocols in the target design. Confirm that the 24A per-channel rating aligns with thermal management requirements. Check for any recent lifecycle status updates or obsolescence notices directly from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a multi-channel solution with integrated digital control is required. The SPI interface allows for complex dimming patterns and fault reporting without additional external logic. Consider the thermal performance of the PG-DSO-36 package under maximum load conditions. Verify that the input voltage range matches the vehicle's power supply characteristics. Evaluate the need for the specific switched capacitor topology versus linear alternatives based on efficiency goals.
