STP08xP05
The STP08xP05 series are monolithic, low-voltage, low-current, low-power LED
drivers and 8-bit shift registers designed for LED panel displays. The STP08xP05
contains an 8-bit serial-in, parallel-out shift register that feeds an 8-bit D-type
storage register. In the output stage, eight regulated current sources provide 5 to
100 mA constant current to drive the LEDs.
Users can adjust LED brightness using an external resistor to control the output
current or using a dedicated digital pin.
The STP08DP05 contains a built-in error-detection feature. This additional function
is achieved without any increase in the pin number and any change in the pin
functions compared to a standard device without error detection.
