Description

The STP16DP05 is a monolithic, low voltage, low

current power 16-bit shift register designed for

LED panel displays. The device contains a 16-bit

serial-in, parallel-out shift register that feeds a 16-

bitD-type storage register. In the output stage,

sixteen regulated current sources were designed

to provide 5-100mA constant current to drive the

LEDs.

The STP16DP05 features open and short LED

detections on the outputs.The STP16DP05 is

backward compatible with STP16C/L596.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.

The detection functionality is implemented without

increasing the pin count 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 STP16DP05 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.

The STP16DP05 guarantees a 20V output driving

capability, allowing users to connect more LEDs in

series. The high clock frequency, 30MHz, makes

the device suitable for high data rate

transmission. The 3.3V voltage supply is well

useful for applications that interface any 3.3V

micro. Compared with a standard TSSOP

package, the TSSOP exposed pad increases heat

dissipation capability by a 2.5 factor.
