AS1113-BQFR

Overview

The AS1113-BQFR is a 16-channel LED driver IC manufactured by ams OSRAM, designed for high-precision lighting control applications. It operates within an input voltage range of 3 V to 5.5 V and supports a maximum output current of 50 mA per channel. The device features a 50 MHz operating frequency and is housed in an SSOP-24 surface-mount package. It functions reliably across a temperature range of -40°C to +85°C and includes humidity sensitivity considerations for storage and handling.

Feature Summary

• Provides independent current regulation for sixteen distinct LED channels
• Integrates serial interface configuration capabilities for system control
• Supports high-frequency operation up to 50 MHz for rapid switching

Applications

• Automotive interior ambient lighting systems
• General-purpose LED matrix illumination arrays
• High-density indicator panel backlighting solutions

Procurement Notes

Verify component authenticity through authorized distribution channels due to the product's end-of-life status. Confirm that the specific suffix matches required packaging formats such as cut tape or reel. Ensure compliance with RoHS directives and validate moisture sensitivity level ratings prior to assembly to prevent damage during soldering processes.

Selection Notes

Select this component when precise multi-channel current control is required for complex LED layouts. Evaluate the SSOP-24 footprint against available board space constraints. Consider the 50 mA output limit and 5.5 V maximum supply voltage to ensure compatibility with the target LED forward voltage requirements and power budget limitations.
