Overview
The AS1109-BSOU is a constant-current LED driver IC manufactured by ams OSRAM AG. It features eight output channels, each capable of delivering up to 100mA. The device operates on a supply voltage range of 3.15V to 5.5V and supports an output voltage of up to 15V. It utilizes a linear topology with shift register control and includes internal switches. The component is housed in a 16-SOIC package (0.154", 3.90mm wide) for surface mount installation. It functions at a frequency of 50MHz and operates within a temperature range of -40°C to 85°C.
Feature Summary
- Provides eight independent constant-current output channels for driving LEDs
- Integrates a fast serial interface for data input and control
- Includes diagnostic capabilities for monitoring circuit status
- Features linear regulation topology with internal switching elements
Applications
- Signage displays
- LED indicator arrays
- Low-power lighting modules
Procurement Notes
Verify the specific suffix BSOU corresponds to the 16-SOIC package variant. Confirm current availability status as the product line may be subject to end-of-life notices. Ensure compatibility with existing PCB footprints and thermal management requirements before finalizing procurement decisions.
Selection Notes
Select this component when eight individually controllable constant-current outputs are required in a compact surface-mount package. Consider the 3.15V to 5.5V supply range and 100mA per channel capability against load requirements. Evaluate the 16-SOIC footprint constraints and operating temperature specifications relative to the target application environment.
Part Context
This part belongs to the AS1109 series of LED drivers from ams OSRAM. It is designed for applications requiring multiple constant-current sources controlled via a serial interface. The series typically includes variants with different pin counts and packages to suit various display and lighting needs.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify functional equivalence with other 8-channel constant-current LED drivers if sourcing alternatives due to potential discontinuation.
