The STAP16DPS05XTTR is a 16-bit low voltage constant current LED Sink Driver with output error detection and auto power-saving. The monolithic low voltage/low current power 16-bit shift register designed for LED panel displays. The device contains a 16-bit serial-in, parallel-out shift register that feeds a 16-bit D-type storage register. In the output stage, sixteen regulated current sources are designed to provide 5 to 100mA constant current to drive the LEDs. The STAP16DPS05 features the open and short LED detections on the outputs. It ensures the backward compatibility with the STP16C/L596. The detection circuit checks 3 different conditions, which can occur on the output line - short to GND, short to VO or open line. The data detection results are loaded in the shift register and shifted out via the serial line output. The detection functionality is implemented without increasing the pin number.
