ST launched a highly integrated RGB driver LED Driver 8 pixels

LED composed of video monitors and billboards, using STP24DP05 to drive, compared to the output channel less traditional devices can save material costs. The new product can effectively reduce the pixel spacing and the distance of the LED lamp group, thus improving the resolution of the display. The main objectives of the application include outdoor and indoor full color RGB video display board, LED billboards, graphic information boards, color traffic lights and a variety of information signs.

STP24DP05 support 25MHz operation, to take serial input, parallel output of the FIFO (first in first out) drive circuit, high-speed serial data rate helps to improve the response speed of the image reduction. Each color group eight output using an external resistor, the driving current regulation of each LED channel in the range of 5-80mA through the resistor, the maximum brightness can be red, green and blue light independent optimization channel. In addition to excellent drive function, the 48 pin TQFP48 package is equipped with a high efficiency heat sink, this feature can improve the flux per watt and system reliability.

STP24DP05 also integrates the internal fault detection function, can detect short ground wire, short circuit power supply or open circuit fault. Through the dedicated pins on the chip can control the fault detection mode, or through the SPI port, the use of special digital keys can also control the fault detection mode. Do not need to add any additional pin, only use the same SPI port, you can export the fault code chip. This feature enables system diagnostics, such as direct alarm to the maintenance coordinator, to effectively reduce system downtime. The STP24DP05 also incorporates a thermal shutdown protection feature that uses a flag pin to transfer the product off state.

The STP24DP05 is manufactured using the ST process of BCD6, rated operating temperature range - 40 to +125 C, compatible with 3.3V and 5V data levels, and improved interoperability with a variety of master controllers, such as the ST7FLITE microcontroller.

STP24DP05 immediate acceptance of production orders.
