Features
Description
The STP16DPP05 is a monolithic, low voltage,
low current power 16-bit shift register designed for
LED panel displays. The device features 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 are designed to
provide 3 to 40 mA of constant current to drive the
LEDs. The STP16DPP05 features open and short
LED detection on the outputs. The detection
circuit checks for 3 different conditions that can
occur on the output line: short to GND, short to V
or open line.

Package
Low voltage 16-bit constant current
The data detection results are loaded in the shift
registers and shifted out via the serial line output.
The detection functionality is implemented without
increasing the pin count, 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 exit from
detection mode. The STP16DPP05 output current
can be adjusted through an external resistor to
control the light intensity of the LEDs.
LED brightness is adjustable from 0% to 100% via
the OE/DM2 pin.
The STP16DPP05 guarantees a 20 V output
driving capability, allowing users to connect more
LEDs in series. The high 30 MHz clock frequency
makes the device suitable for high data rate
transmission. The 3.3 V supply is well suited for
applications which interface a 3.3 V MCU.
Compared to a standard TSSOP package, the
TSSOP with exposed pad increases heat
dissipation capability by a factor of 2.5
