Description
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 VO or open line. 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.
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
