Description
The STP16DPS05 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.

STP16DPS05
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 LATCH and output
enable 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
STP16DPS05 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
OE/DM2 pin.
The STP16DPS05 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 STP16DPS05
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 14. 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.
16/34 Doc ID 16538 Rev 2
STP16DPS05 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 microcontroller switches the OE/DM2
to analyze if an OPEN or SHORT condition has occurred.
Figure 15. Detection diagram
to LOW, the device drives the LEDs in order
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.
