The STP08DP05 is a monolithic, low voltage, low current power 8-bit shift register designed for LED panel displays. It contains a 8-bit serial-in, parallel-out shift register that feeds a 8-bit D-type storage register. Eight regulated current sources were designed to provide 5-100 mA constant current to drive the LEDs. The STP08DP05 is backward compatible with STP8C/L596 and extends its functionality with open and short detection on the outputs. The detection circuit checks for three different conditions 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, using a secondary function of the output enable and latch pin (DM1 and DM2 respectively).
The STPO8DP05 is a monolithic, low voltage, low current power 8-bit shift register designed for LED panel displays. It contains an 8-bit serial-in, parallel-out shift register that feeds an 8-bit D-type storage register. The output stage provides eight regulated current sources to drive LEDs with a constant current ranging from 5 to 100 mA.
The device features short and open output error detection, checking for shorts to GND, shorts to Vop, or open lines. It is backward compatible with the STP8C/L596 and extends functionality with detection circuits implemented without increasing the pin count. Users can adjust the output current via an external resistor and control brightness from 0% to 100% via the OE/DM2 pin.
