ST STP08DP05 Low voltage 8-bit constant current LED sink with full outputs error detection handbook
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.
