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). 16 constant current output channels
