STEVAL-ILL002V4

STEVAL-ILL002V4 High-brightness LED driver with diagnostics (40 LEDs) demonstration board based on the STP08DP05 Data brief Features Brightness regulation Blinking speed regulation Animated text Error detection on output Graphic user interface (GUI) DC-DC converter Description STEVAL-ILL002V4 This demonstration board provides a complete solution for driving 40 high-brightness green LEDs manufactured by Toshiba. The high-brightness LEDs are arranged on the board in a 5x8 matrix. The matrix is driven by five 8-channel STP08DP05 drivers which are controlled by the ST7FLITE3x 8-bit microcontroller. The innovative feature of STP08DP05 is the full output error detection function, which checks the status of the outputs without invasive tests (via software).
