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 5-100 mA 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 VO or open

line. The data detection results are loaded in the

shift register and shifted out via the serial line

output.

 Low voltage power supply down to 3 V

 8 constant current output channels

 Adjustable output current through external

resistor

 Short and open output error detection

 Serial data IN/parallel data OUT

 3.3 V micro driver-able

 Output current: 5-100 mA

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’s brightness

intensity from 0% to 100% via OE/DM2 pin.

driving capability, allowing users to connect more

LEDs in series. The high clock frequency,

30 MHz, also satisfies the system requirement of

high volume data transmission. The 3.3 V of

panel displays. The STP08DP05 contains a 8-bit

standard TSSOP package, the TSSOP exposed

pad increases heat dissipation capability by a 2.5

factor.
