The STP24DP05BTR is a 24-bit constant current LED Sink Driver with output error detection. The monolithic, low-voltage low current shift register designed for LED panel displays. The device contains an 8 x 3-bit serial-in, parallel-out shift register that feeds a 8 x 3-bit D-type storage register. In the output stage, twenty four regulated current sources were designed to provide 5 to 80mA constant current to drive the LEDs. The 8 x 3 shift register data flow sequence order can be managed through two dedicated pins. The STP24DP05 has a dedicated pin to activate the outputs with a sequential delay, that prevents inrush current during output turn-ON. The device detection circuit checks 3 different conditions that can occur on the output line: short to GND, short to VO or open line. The data detection results are loaded in the shift registers and shifted out via the serial line output.
