LED Driver Powers Displays

Wed, 08/06/2008 - 10:08am

STM STP24DP05Offering 24 constant-current outputs capable of driving from 5 to 80 mA each at 25 MHz, STMicroelectronics’ STP24DP05 RGB LED driver supplies light to video displays, billboards, graphic boards, colored traffic signs and variable message signs. The serial-in parallel-out FIFO uses built-in error detection controlled for short-to-ground, short-to-supply or open-line faults, which are shifted out via a SPI port with no additional pin. The 7-mm² 48-pin TQFP48-packaged device has compatibility with 3.3- and 5-V data levels, specified in a temperature range from -40ºC to 125ºC and an exposed pad for heat dissipation. Pricing starts at $1.50 in quantities of 100,000 and up.
