AS1109-BSST

Overview

The AS1109-BSST is a linear LED driver IC manufactured by ams OSRAM AG, designed for signboard applications. It features an 8-bit shift register topology with eight constant-current output channels, each capable of delivering up to 100mA. The device operates within a supply voltage range of 3V to 5.5V and supports a maximum output voltage of 15V per channel. It utilizes a fast serial interface for control and includes internal switches. The component is housed in a 24-SSOP package (0.154" width) and functions reliably across a temperature range of -40°C to 85°C.

Feature Summary

Integrates eight independent constant-current drivers for precise LED regulation
Utilizes a linear shift register topology for simplified serial control
Includes diagnostic capabilities for enhanced system monitoring

Applications

Signboard illumination systems
LED display modules requiring serial control
Low-power indicator lighting arrays

Procurement Notes

Verify the specific suffix 'BSST' against the manufacturer's current datasheet to confirm pinout compatibility and package dimensions. Confirm RoHS compliance status as required by your assembly specifications. Check for End-of-Life notifications or alternative part recommendations from ams OSRAM AG before finalizing procurement plans.

Selection Notes

Select this component when designing circuits that require eight individually addressable LED channels with moderate current drive capabilities. Ensure the host microcontroller supports the required serial interface protocol. Verify that the thermal management solution accommodates the power dissipation characteristics of the linear topology under maximum load conditions.

Part Context

This part belongs to the AS11xx series of LED drivers from ams OSRAM AG, which are optimized for signage and display applications. The series typically offers various channel counts and packaging options to suit different design constraints while maintaining consistent control interfaces and performance characteristics.

Replacement Considerations
