Features
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

Package
Low voltage 16-bit constant current
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
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.
