  • The STP24DP05 is a monolithic, low-voltage, low current power 24-bit 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 5-80 mA 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.
    The detection functionality is activated with a dedicated pin or alternatively, through a logic sequence that allows the user to enter or exit detection mode.
    Through three external resistors, the user can adjust the output current for each 8-channel group, therefore controlling the light intensity of LEDs.
    The STP24DP05 guarantees a 20 V output driving capability, allowing the user to connect more LEDs in series.
    The high clock frequency, 25 MHz, makes the device suitable for high data rate transmission.
    The 3.3 V of voltage supply is useful for applications that interface any microcontroller from 3.3 V.
