STP24DP05  
24-bit constant current  
LED sink driver with output error detection  
Features  
Low voltage power supply down to 3 V  
8 x 3 constant current output channels  
Adjustable output current through external  
resistors  
Short and open output error detection  
Serial data IN/Parallel data OUT  
Shift register data flow registers control  
Accepts 3.3 V and 5 V micro driver  
Output current: 5-80 mA  
TQFP48  
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 as alternative, through a logic  
sequence that allows the user to enter or exit from  
detection mode.  
25 MHz clock frequency  
High thermal efficiency package  
Through three external resistors, users can adjust  
the output current for each 8-channel group,  
controlling in this way the light intensity of LEDs.  
Description  
The STP24DP05 is a monolithic, low voltage, low  
current power 24-bit shift register designed for  
LED panel displays. The device contains a  
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 STP24DP05 guarantees a 20 V output  
driving capability, allowing users 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 micro from 3.3 V.  
The 8x3 shift registers data flow sequence order  
can be managed with two dedicated pins.  
The STP24DP05 has a dedicated pin to activate  
the outputs with a sequential delay, that will  
prevent inrush current during outputs turn-ON.  
The device detection circuit checks 3 different  
conditions that can occur on the output line: short  
to GND, short to V or open line.
