The detection functionality is implemented without
increasing the pin number, 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 leave from
detection mode. Through an external resistor,
users can adjust the STP08DP05 output current,
controlling in this way the light intensity of LEDs,
in addition, user can adjust LED鈥檚 brightness
intensity from 0% to 100% via
OE/DM2
pin.
The STP08DP05 guarantees a 20V output driving
capability, allowing users to connect more LEDs in
series. The high clock frequency, 30MHz, also
satisfies the system requirement of high volume
data transmission. The 3.3V of voltage supply is
well useful for applications that interface any
micro from 3.3V. Compared with a standard
TSSOP package, the TSSOP exposed pad
increases heat dissipation capability by a 2.5
factor..

Description
The STP08DP05 is a monolithic, low voltage, low
current power 8-bit shift register designed for LED
panel displays. The STP08DP05 contains a 8-bit
serial-in, parallel-out shift register that feeds a 8-
bitD-type storage register. In the output stage,
eight regulated current sources were designed to
provide 5-100mA constant current to drive the
LEDs.
The STP08DP05 is backward compatible in the
functionality and footprint with STP8C/L596 and
extends its functionality with open and short
detection on the outputs. The detection circuit
checks 3 different conditions that can occur on the
output line: short to GND, short to V
O
or open line.
The data detection results are loaded in the shift
register and shifted out via the serial line output.
