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 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.
