AS3824E1-ZQFM

Overview

The AS3824E1-ZQFM is a linear LED driver manufactured by Renesas Electronics Corporation, packaged in a 48-QFN (7x7 mm) with an exposed pad. It features 16 output channels and supports SPI interface control for backlight applications. The device operates within a junction temperature range of -20°C to 115°C and utilizes surface mount installation.

Feature Summary

• Linear topology for precise current regulation
• SPI interface for digital control
• High channel count integration

Applications

• Backlight systems

Procurement Notes

Verify the manufacturer designation carefully, as this specific part number is documented under Renesas Electronics Corporation rather than ams-OSRAM USA INC. Confirm the suffix ZQFM corresponds to the required tape and reel packaging configuration distinct from other variants like ZQFT. Ensure compatibility with the specified 48-QFN footprint during procurement validation.

Selection Notes

Select this component when designing high-density backlight circuits requiring independent channel control via a serial interface. The linear architecture suits applications where efficiency is secondary to simplicity and low noise. Verify that the thermal management design accommodates the 115°C maximum junction temperature limit for reliable operation in enclosed environments.

Part Context

This integrated circuit belongs to the family of multi-channel LED drivers designed for display illumination. It provides a compact solution for managing multiple LED strings in a single package. The QFN form factor facilitates automated assembly and reduces the overall board space required for complex lighting arrays in consumer electronics.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Cross-reference tools indicate potential alternatives exist but require verification against specific electrical parameters and pinout configurations before implementation.
