Overview
The AS1112-BQFT is an automotive-grade, standalone intelligent LED driver IC designed for high-reliability lighting applications. Manufactured by ams OSRAM, this component features nine independent output channels capable of driving LEDs with precise current regulation. It operates within a supply voltage range of 4.3 V to 5.5 V and supports Pulse Width Modulation (PWM) dimming for brightness control. The device is housed in a compact QFN-16 package, ensuring suitability for space-constrained automotive environments while maintaining robust thermal performance across the specified operating temperature range.
Feature Summary
- Automotive-grade reliability compliant with AEC-Q100 standards
- Nine independent constant current output channels
- Integrated PWM dimming functionality for precise brightness control
- Standalone operation requiring minimal external components
Applications
- Automotive interior ambient lighting systems
- Vehicle exterior signature lighting elements
- High-reliability automotive indicator circuits
Procurement Notes
Verify the specific suffix 'BQFT' against official ams OSRAM documentation to confirm package type and tape-and-reel specifications. Ensure compliance with RoHS directives and check for updated lifecycle status or obsolescence notices directly from the manufacturer before finalizing procurement plans.
Selection Notes
Select this component when designing automotive lighting circuits requiring nine independently controlled outputs. Verify that the system power supply remains within the 4.3 V to 5.5 V operational window. Confirm that the QFN-16 footprint aligns with the PCB layout constraints and thermal management requirements of the target application.
Part Context
This part belongs to the FIREFLY family of intelligent LED drivers from ams OSRAM, specialized for automotive use. These ICs integrate advanced protection features and diagnostic capabilities typical of the series, distinguishing them from general-purpose consumer LED drivers through enhanced durability and functional safety characteristics required for vehicle integration.
Replacement Considerations
Consult official cross-reference lists for direct substitutes. Verify pin compatibility and electrical parameters if considering alternative manufacturers.
