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 V
O
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.
