Overview
The AS3823-ZTQT is a linear LED driver IC featuring six independent outputs with SPI dimming control, housed in a 32-TQFP package. It supports high-precision current regulation for multi-channel LED arrays, enabling uniform brightness across complex lighting configurations. The device integrates protection mechanisms against over-temperature and open-load conditions to ensure reliable operation in demanding automotive and industrial environments.
Feature Summary
- Six-output linear architecture for precise individual channel control
- Serial Peripheral Interface (SPI) enables digital dimming and configuration
- Integrated thermal and fault protection for system robustness
Applications
- Automotive interior ambient lighting systems
- Multi-zone display backlighting drivers
- Industrial indicator array control
Procurement Notes
Verify the specific suffix 'ZTQT' matches the required tape-and-reel packaging quantity and lead time specifications from the manufacturer's official distribution channels. Confirm that the 32-TQFP footprint aligns with your PCB design constraints before finalizing procurement orders.
Selection Notes
Select this component when a multi-channel solution requires precise analog current matching without complex PWM switching noise. It is suitable for applications where digital control via SPI is preferred over parallel analog inputs, offering a balance between complexity and performance for medium-density LED arrays.
Part Context
This part belongs to ams OSRAM's portfolio of specialized lighting control solutions designed for high-reliability sectors. It complements their broader ecosystem of LEDs and sensors by providing the necessary drive electronics for sophisticated illumination projects requiring synchronized multi-channel management.
Replacement Considerations
No direct public substitute part numbers are confirmed for this specific variant. Evaluate alternative drivers based on output count, package type, and interface compatibility if substitution is required.
