STEVAL-ILL0V H LED driver with diagnostic based on the LED Description Data brief The STEVAL-ILL0V evaluation board provides a platform to test and evaluate STMicroelectronics LED LED driver. The LED device is a -bit constantcurrent LED sink driver with output error detection, suitable for applications such as largearea displays and full-color board panels where improvement in LED resolution and reduction of system costs are important. Features Two LED devices in TQFP package connected to x high-brightness LEDs STM microcontroller ost-effective internal high-side oscillator JTA interface for microcontroller firmware changes/updates Mini US connector for connection with a P UI Test points on the board for each important signal aids laboratory evaluation uttons and knob to control the board Error and overtemperature flag for each LED driver jumpers to simulate the disconnection of LEDs jumpers to simulate the shorting of LEDs Highly-efficient STS00 D-D switching power supply Input:. V to V, 0. A ohs compliant July 0 DocID0 ev / For further information contact your local STMicroelectronics sales office. www.st.com
