Overview
The AS1112B-BQFT is a 16-channel LED driver IC manufactured by ams-OSRAM USA INC. It features linear shift register dimming with a maximum output current of 100mA per channel and supports up to 30V output voltage. The device is housed in a 32-TQFN (5x5) surface-mount package. It operates within a temperature range of -40°C to +85°C and requires a supply voltage between 2.7V and 3.6V. This component is designed for high-quality lighting applications requiring precise control.
Feature Summary
- Provides 16 independent output channels for individual LED control
- Integrates dot correction functionality for uniform brightness across the array
- Utilizes linear shift register architecture for simplified serial interface operation
- Supports high-brightness requirements suitable for public and private transport environments
Applications
- Public passenger transport interior lighting
- Private passenger transport interior lighting
- High-brightness signage arrays
- Automotive ambient lighting systems
Procurement Notes
Verify component authenticity through authorized distribution channels due to obsolete lifecycle status. Confirm pin compatibility and thermal performance against original design specifications before integration. Ensure supply chain stability as replacement sourcing may require validation of equivalent functional parameters from alternative manufacturers.
Selection Notes
Select this component when 16-channel precision control is required for high-brightness LED matrices. The integrated dot correction simplifies calibration processes compared to non-corrected drivers. Consider the 32-TQFN footprint for space-constrained PCB layouts. Evaluate thermal dissipation requirements given the linear regulation method and 100mA per channel capability.
Part Context
This part belongs to the AS1112 family of LED drivers, which are specialized for automotive and transport lighting applications. The 'B' suffix typically denotes specific binning or revision characteristics within the series. These drivers are engineered to meet stringent quality standards for vehicle interiors, ensuring reliability under varying environmental conditions.
Replacement Considerations
AS1112-BQFT is a related variant offering 16 outputs with 100mA current but lacks the 'dot correction' feature explicitly mentioned for the B-series. Verify if dot correction is mandatory for the application before substituting.
