SC4541SKTRT

Overview

The SC4541SKTRT is a high-frequency LED driver manufactured by Semtech Corporation, designed for automotive applications. It features an integrated Schottky diode and supports simple interconnect configurations. The device operates as a 7-segment LED driver with a supply current of 3000uA. It is housed in a compact 6-pin SOT-23 package and supplied in tape and reel format.

Feature Summary

• Integrates a Schottky diode to simplify circuit design
• Optimized for high-frequency LED driving operations
• Supports simple interconnect architectures for reduced component count

Applications

• Automotive lighting systems
• 7-segment LED display drivers
• High-frequency LED control circuits

Procurement Notes

Verify the specific suffix SKTRT confirms the SOT-23 package and tape-and-reel shipping method. Confirm automotive qualification status if required by the application environment. Ensure compatibility with the intended 7-segment LED load requirements before finalizing procurement.

Selection Notes

Select this component when a compact solution for automotive LED driving is required. The integrated Schottky diode reduces external component count compared to discrete solutions. Consider the 6-pin SOT-23 footprint for space-constrained PCB layouts requiring high-frequency operation.

Part Context

This part belongs to the SC4541 series of high-frequency LED drivers from Semtech. The series includes variants such as SC4541ULTRT, which utilizes an MLPD-UT EP package. Both variants share the core functionality of driving 7-segment LEDs with low supply current in automotive environments.

Replacement Considerations

SC4541ULTRT serves as a package alternative within the same functional family, utilizing an MLPD-UT EP package instead of SOT-23.
