Description
The STP16CPC26 is a monolithic, low voltage,
16-bit constant current LED sink driver. The
device contains a 16-bit shift register and data
latches, which convert serial input data into
parallel output format. In the output stage sixteen
regulated current generators provide 5 mA to 90
mA constant current to drive LEDs. The current is
externally adjusted through a resistor. LED
brightness can be adjusted from 0% to 100% via
OE pin.

The STP16CPC26 guarantees a 20 V driving
capability, allowing users to connect more LEDs in
series to each current source.
The high 30 MHz clock frequency makes the
device suitable for high data rate transmission.
The thermal shutdown (170°C with about 15°C
hysteresis) assures protection from
overtemperature events.
The STP16CPC26 is housed in four different
packages: QSOP24, SO-24, TSSOP-24 and
HTSSOP-24 (with exposed pad).
