AS1115-BSST

Overview

The AS1115-BSST is a compact, I²C interfaced dot-matrix LED driver designed for an 8x8 LED matrix or eight 7-segment displays. It features 64 current sinks with 4-bit PWM per segment and external resistor-controlled analog current adjustment up to 5mA per LED. The device operates on a supply voltage range of 2.7V to 5.5V, supports a maximum forward current of 47mA, and includes 16-key readback capabilities alongside detailed short/open LED error diagnostics.

Feature Summary

• I²C interface for simplified user interface implementation
• Integrated 4-bit PWM for individual brightness control
• External resistor-based analog current adjustment
• Built-in diagnostic for LED short and open circuit detection

Applications

• 8x8 LED matrix display systems
• Multi-digit 7-segment display panels
• White goods control interfaces
• Computing equipment indicator panels

Procurement Notes

Verify the specific ordering code Q65114A0654 against official ams OSRAM documentation to confirm availability status. Ensure compatibility with the required QSOP24 or TQFN24 package variant. Confirm RoHS compliance requirements match the target application standards before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring direct I²C control of high-density LED arrays. The integrated PWM and diagnostic features reduce external component count. Verify that the host microcontroller supports the necessary I²C communication protocol and that the application environment remains within the specified operating temperature range.
