Overview
The AS1163B-AQFM is a 9-output standalone intelligent LED driver IC from ams OSRAM, designed for automotive dynamic lighting applications. It operates within a supply voltage range of 4.3 V to 5.5 V and supports PWM dimming with up to 16-bit resolution per channel. The device features a QFN-16 package and functions across an extended temperature range from -40°C to +125°C. It complies with RoHS3 standards and holds an MSL rating of 3.
Feature Summary
- Supports complex dynamic lighting effects through daisy-chain configurations compatible with the Open System Protocol (OSP).
- Integrates comprehensive diagnostic capabilities including open/short circuit detection, overvoltage protection, and overtemperature protection.
- Functions as an I²C gateway, allowing connected microcontrollers to access external peripherals such as EEPROMs and sensors.
Applications
- Automotive exterior dynamic lighting systems
- Interior ambient lighting control modules
- Smart LED matrix architectures requiring high-resolution dimming
Procurement Notes
Verify the specific suffix AQFM against the manufacturer's current datasheet to confirm pinout and thermal pad specifications. Ensure the ordering quantity aligns with the standard reel size of 5,000 units. Confirm that the design environment meets the required Moisture Sensitivity Level (MSL) handling procedures before assembly.
Selection Notes
Select this component when designing automotive lighting systems requiring independent control of multiple LED channels with high dynamic range. It is suitable for applications needing robust fault diagnostics and communication via OSP or I²C. Consider the AS1163 variant if the application requires three-channel RGB triplets instead of the two-channel configuration supported by the AS1163B series.
Part Context
This part belongs to the SAID2 family of intelligent LED drivers, specifically optimized for automotive environments. It complements other ams OSRAM components like the OSIRE E3731i controller. The device integrates mixed-signal silicon technology to provide precise current regulation and advanced communication interfaces for modern vehicle lighting networks.
Replacement Considerations
The AS1163 serves as a functional alternative for designs requiring three-channel RGB outputs. Verify compatibility with existing PCB footprints and software drivers when substituting between SAID and SAID2 variants due to potential differences in output organization.
