STEVAL-ILL058V1 High brightness LED array driver with diagnostics for automotive applications based on the STAP08DP05 and STM8A Data brief Description The STEVAL-ILL058V1 evaluation board is a high brightness LED array driver application with diagnostics based on the automotive grade, low voltage, 8-bit constant current LED sink driver STAP08DP05 from STMicroelectronics. The LED driver is configured and controlled through an 8-bit automotive grade STM8A microcontroller via SPI interface. An automotive grade A5974D DC-DC converter provides the voltages and power for the overall functioning of the board. Features 6 - 24 V DC power supply with reverse voltage protection, short-circuit protection and standard DC jack input Backward/forward transition switch and reset switch SWIM connector to program microcontroller and for debugging purposes Connector for LIN development and evaluation Brightness control potentiometer Speed control potentiometer 40 white LEDs (PLCC 4) 8 jumpers to simulate open-circuit errors 4 jumpers to simulate short-circuit errors Slot for USB-to-UART daughterboard Demonstrates pre-configured patterns (dot- sequence, backlighting, alphanumeric text etc.) in stand-alone mode Demonstrates basic mode or frame programming mode with GUI SW RoHS compliant August 2014 DocID025924 Rev 1 1/7 For further information contact your local STMicroelectronics sales office. www.st.comSchematic diagrams STEVAL-ILL058V1 1 Schematic diagrams Figure 1.
