Overview
The AS1163-AQFT is a standalone intelligent LED driver IC designed for automotive dynamic lighting applications. It features nine independent output channels organized as three RGB triplets, supporting up to 16-bit PWM dimming resolution per channel. The device operates within a supply voltage range of 4.3 V to 5.5 V and functions reliably across an extended temperature range from -40°C to +125°C. Packaged in a QFN-16 form factor, it integrates diagnostic capabilities including open/short circuit detection and overvoltage protection.
Feature Summary
- Supports dynamic lighting through independent 16-bit PWM control for each of the nine output channels
- Enables complex lighting effects via daisy-chain or star topology communication compatible with OSIRE protocols
- Integrates comprehensive hardware diagnostics for fault detection and system safety monitoring
Applications
- Automotive exterior dynamic lighting systems
- Multi-channel RGB LED color mixing modules
- Smart lighting nodes requiring I2C gateway functionality
Procurement Notes
Verify the complete part number against manufacturer documentation to ensure correct package and tape-and-reel specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to assembly planning. Cross-reference ordering codes with authorized distributors to validate current product availability and lifecycle status.
Selection Notes
Select this component when designing automotive lighting systems requiring high-resolution individual channel control. It is suitable for applications needing robust diagnostic feedback and secure communication interfaces. Consider the QFN-16 footprint constraints and thermal management requirements associated with the specified operating temperature range during PCB layout.
Part Context
This device belongs to the AS1163 family of SAID (Standalone Intelligent Driver) ICs developed by ams OSRAM. These mixed-signal silicon devices are optimized for automotive-grade dynamic illumination. The series includes variants like the AS1163B for different channel configurations, all sharing common communication protocols and diagnostic features for scalable lighting architectures.
Replacement Considerations
Consult official substitution lists for equivalent automotive LED drivers. Verify pin compatibility and electrical characteristics before replacing existing components in production designs.
