Overview
The AS1163-AQFM is a standalone intelligent LED driver IC designed for automotive dynamic lighting applications. It features nine independent output channels capable of driving LEDs organized in three RGB triplets or as single-color units. The device supports up to 16-bit PWM dimming resolution per channel, enabling high-precision color mixing and intensity control. Operating within a supply voltage range of 4.3 V to 5.5 V, it functions reliably across an extended temperature range from -40°C to +125°C. The component utilizes a QFN-16 package and integrates diagnostic capabilities for open/short circuits and overvoltage protection.
Feature Summary
- Supports dynamic lighting through independent 16-bit PWM dimming for precise color and intensity control
- Enables complex system architectures via bidirectional two-wire daisy-chain or star topology communication
- Integrates comprehensive fault detection including open circuit, short circuit, overvoltage, and overtemperature diagnostics
Applications
- Automotive exterior dynamic lighting systems
- Interior ambient lighting with color tuning
- Multi-channel LED matrix configurations
Procurement Notes
Verify the specific suffix AQFM against official datasheets to confirm pinout and electrical characteristics match the design requirements. Ensure compatibility with the Open System Protocol (OSP) if integrating with other OSIRE components. Confirm RoHS compliance status and moisture sensitivity level (MSL 3) for assembly process planning. Cross-reference the manufacturer part number with distributor listings to avoid confusion with similar variants like AS1163B.
Selection Notes
Select this component when designing automotive lighting systems requiring independent control of multiple LED channels with high-resolution dimming. It is suitable for applications needing robust diagnostic feedback and secure communication topologies. Consider the QFN-16 package constraints for PCB layout and thermal management. Evaluate the need for I²C gateway functionality if external sensors or memory devices must be accessed through the driver chain.
Part Context
The AS1163 belongs to the SAID (Standalone Intelligent Driver) family developed by ams OSRAM. This series targets advanced automotive illumination needs, offering silicon-based solutions that replace discrete driver components. The AS1163 variant specifically provides nine outputs, distinguishing it from the six-output AS1163B model. Both models support functional safety concepts at the system level while adhering to quality management standards.
Replacement Considerations
AS1163B is a related variant with six outputs instead of nine. Verify output count requirements before substitution. No direct public substitute part numbers are confirmed for this specific nine-channel configuration.
