High brightness RGB LED array with LED error detection based on the STP24DP05 and STM32

The STEVAL-ILL015V1 demonstration board provides a platform for the testing and evaluation of STMicroelectronics’ Power Logic LED driver STP24DP05.

The STP24DP05 device is a 24-bit constant current LED sink driver with output error detection, suitable for applications such as largearea displays and full-color board panels where improvement in RGB LED resolution and reduction of system cost are important.

Key Features

  • 3 jumpers to simulate the shorting of 3 LEDs
  • 3 jumpers to simulate the disconnection of 3 LEDs
  • Input 7.5 V - 18 V, current 0.7 A
  • Highly efficient ST1S010 DC-DC switching power supply
  • Buttons and knob to control the board
  • Test points on the board for each important signal aide laboratory evaluation
  • Two STP24DP05 devices (TQFP48 package) connected to 3 X 16 RGB high brightness LEDs
  • Using a cost-effective internal HS oscillator.
  • STM32 microcontroller
  • Mini USB connector for interconnection with a PC GUI.
  • Error and over-temperature flag for each LED driver
  • JTAG interface for microcontroller firmware changes/updates
