Description
The STP16DP05 is a monolithic, low voltage, low
current power 16-bit shift register designed for
LED panel displays. The device contains a 16-bit
serial-in, parallel-out shift register that feeds a
16-bit D-type storage register. In the output stage,
sixteen regulated current sources were designed
to provide 5-100 mA constant current to drive the
LEDs.
The STP16DP05 features open and short LED
detections on the outputs.The STP16DP05 is
backward compatible with STP16C/L596.The
detection circuit checks 3 different conditions that
can occur on the output line: short to GND, short
to V
or open line.

Table 1. Device summary
STP16DP05
Low voltage 16-bit constant current
QSOP-24
TSSOP24
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 count number, through a
secondary function of the output enable and latch
pin (DM1 and DM2 respectively), a dedicated
logic sequence allows the device to enter or leave
from detection mode. Through an external
resistor, users can adjust the STP16DP05 output
current, controlling in this way the light intensity of
LEDs, in addition, user can adjust LED’s
brightness intensity from 0% to 100% via
pin.
The STP16DP05 guarantees a 20 V output
driving capability, allowing users to connect more
LEDs in series. The high clock frequency,
30 MHz, makes the device suitable for high data
rate transmission. The 3.3 V voltage supply is well
useful for applications that interface any 3.3V
micro. Compared with a standard TSSOP
package, the TSSOP exposed pad increases heat
dissipation capability by a 2.5 factor.

Detection mode functionality STP16DP05
7 Detection mode functionality
7.1 Phase one: “entering in detection mode“
From the “normal mode” condition the device can switch to the “error mode” by a logic
sequence on the OE\DM2
Table 12. Entering in detection truth table
CLK1°2°3°4°5°
and LE/DM1 pins as showed in the following table and diagram:
OE/DM2
HLHHH
LE/DM1 LLLHL
Figure 15. Entering in detection timing diagram
After these five CLK cycles the device goes into the “error detection mode” and at the 6th
rise front of CLK the SDI data are ready for the sampling.
16/31 Doc ID 13093 Rev 6
STP16DP05 Detection mode functionality
7.2 Phase two: “error detection”
The 16 data bits must be set “1” in order to set ON all the outputs during the detection. The
data are latched by LE/DM1 and after that the outputs are ready for the detection process.
When the micro controller switches the OE\DM2
order to analyze if an OPEN or SHORT condition has occurred.
Figure 16. Detection diagram
to LOW, the device drives the LEDs in
The LEDs status will be detected at least in 1 microsecond and after this time the
microcontroller sets OE\DM2
in HIGH state and the output data detection result will go to
the microprocessor via SDO.
Detection mode and normal mode use both the same format data. As soon as all the
detection data bits are available on the serial line, the device may go back to normal mode
of operation. To re-detect the status the device must go back in normal mode and reentering in error detection mode.
