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-bit D-type storage register. In the output
stage, sixteen regulated current sources were
designed to provide 5-100 mA 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 20 V output driving capability,
allowing users to connect more LEDs in series.
The high clock frequency, 30 MHz, makes the
device suitable for high data rate transmission.
The 3.3 V voltage supply is well useful for
applications that interface any 3.3 V micro.
Compared with a standard TSSOP package, the
TSSOP exposed pad increases heat dissipation
capability by a 2.5 factor.
