BCR401UE6327HTSA1

Overview

The BCR401UE6327HTSA1 is a linear LED driver IC manufactured by Infineon Technologies. It operates with an input voltage range of 1.4V to 40V and provides three independent current outputs. The device supports PWM dimming for brightness control and features a low dropout voltage characteristic. It is housed in a surface-mount SC-74-6 package, designed for efficient power management in lighting applications requiring multiple channel regulation.

Feature Summary

• Supports three independent output channels for multi-LED configurations
• Enables precise brightness control via external PWM dimming signals
• Operates effectively across a wide input voltage spectrum up to 40V

Applications

• Multi-channel LED lighting systems
• Automotive interior illumination modules
• General-purpose constant current LED drivers

Procurement Notes

Verify the specific suffix HTSA1 against official Infineon documentation to confirm pinout and thermal characteristics. Confirm availability status as distribution data may indicate obsolete or end-of-life conditions. Ensure compatibility with SC-74-6 footprint requirements during PCB layout. Cross-reference datasheet revisions for any updates to electrical limits or recommended operating conditions before finalizing procurement.

Selection Notes

Select this component when designing circuits requiring three separate regulated current paths from a single supply rail. The wide input voltage range accommodates varying source conditions without additional regulation stages. Consider the SC-74-6 package size constraints relative to available board space. Verify that the required PWM frequency falls within the operational limits specified in the technical documentation.

Part Context

This part belongs to the BCR401 series of LED drivers from Infineon Technologies. The series includes variants such as BCR401RE6327HTSA1, which differs in package type and channel configuration. The UE6327HTSA1 designation specifically identifies the three-channel version in the SC-74-6 package, distinguishing it from other family members with different output counts or housing styles.

Replacement Considerations

Direct substitutes include other BCR401 series variants if channel count and package match. Check for equivalent three-channel linear LED drivers from other manufacturers only if pin-to-pin compatibility is verified through official cross-reference documents.
