STEVAL-ILL060V1
High brightness LED array driver with diagnostics for automotive
applications based on the STAP16DPPS05 and STM8A
Data brief
Description
The STEVAL-ILL060V1 is a high brightness LED
array driver evaluation board with diagnostics
based on STMicroelectronics’ automotive-grade
low voltage, 16-bit constant current LED sink
driver STAP16DPPS05.
The LED driver is configured and controlled
through an 8-bit automotive-grade STM8A
microcontroller via an SPI interface. An A5974D
DC-DC converter, also automotive-grade,
provides the voltages and power needed for
overall operation of the board.
Features
•
6 - 24 VDC power supply with reverse voltage
protection, short-circuit protection and input
surge protection and standard DC jack input
•
Backward/forward transition switch to change
modes
•
SWIM connector for MCU programing and
debugging
•
Connector for LIN development and evaluation
•
Potentiometer to change brightness and speed
of patterns
•
32 white LEDs (PLCC 4)
•
8 jumpers to simulate open-circuit error
•
4 jumpers, to simulate short-circuit error
•
USB-UART bridge to interface board with GUI
•
Demonstrates pre-configured patterns (with
adjustable brightness/speed) such as rolling
text, wave effect, dot sequence, etc. in stand-
alone mode
•
Demonstrates basic mode or frame
programming mode with GUI SW
•
RoHS compliant
