8-pixel high-integration single-chip RGB LED driver drives

A drive current up to 80mA constant current output of 24 Road, RGB LED drive device STP24DP05. 7 x 7mm in a TQFP48 package of new products, the effectiveness of the equivalent of three 8-channel output common drive. By the composition of many high-brightness LED video displays and billboards, the use of STP24DP05 driven output channel less than the traditional material cost-saving device. New products can effectively reduce the pixel pitch and LED lights group spacing, thereby increasing the resolution of the display. The main target applications include outdoor and indoor full-color RGB video display panels, LED advertisement billboards, graphic information panels, traffic lights and all kinds of color information signs. STP24DP05 support 25MHz operation, to take serial input, parallel output FIFO (FIFO) driver circuit, the high-speed serial data rate reduction will help improve the image of the response speed. Each color group of eight output using an external resistor, this resistor can be in the range of 5-80mA channels regulate the driving of each LED current can be optimized

independent red, green and blue channels of the greatest brightness. Apart from the outstanding features of the drive, 48-pin TQFP48 package with high-performance thermal pad, the features can improve the flux-per-watt and system reliability. STP24DP05 also integrates an internal fault detection capabilities, can detect a short grounding line, the power shorted or open circuit fault. Through a dedicated pin on a chip can control the fault detection mode, or through the SPI port, the use of special keys can also control the number of fault detection mode. Without adding any additional pin, only to use the same SPI port, the fault code can be derived chips. The characteristics of a system diagnostic features, such as maintenance coordinator to direct the police to effectively reduce system downtime. STP24DP05 also integrated thermal shutdown protection function, the use of a sign-off pin state transmission products. BCD6 using ST's STP24DP05 process, the rated operating temperature range of -40 ℃ to +125 ℃, compatible with 3.3V and 5V data levels, and increased the main controller with a wide range of interoperability, such as 8-bit microcontroller ST7FLITE .
