Description
The STP16CPPS05 is a monolithic, low voltage,
low current power 16-bit shift register designed
for LED panel displays. The device features 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 are
designed to provide 3 to 40 mA of constant
current to drive the LEDs.
The STP16CPPS05 output current can be
adjusted through an external resistor to control
the light intensity of the LEDs. LED brightness is
adjustable from 0% to 100% via the OE pin.
The auto power-shutdown and auto power-ON
feature allows the device to save power with no
external intervention.
The STP16CPPS05 guarantees a 20 V output
driving capability, allowing users to connect more
LEDs in series. The high 30 MHz clock frequency
makes the device suitable for high data rate
transmission. The 3.3 V supply is well suited for
applications which interface a 3.3 V MCU.
Compared to a standard TSSOP package, the
TSSOP with exposed pad increases heat
dissipation capability by a factor of 2.5.
