Overview
The STP16CPC26 is a monolithic, low voltage, 16-bit constant current LED sink driver produced by STMicroelectronics. This device contains a 16-bit shift register and data latches that convert serial input data into parallel output format. It features sixteen regulated current generators, each capable of providing a constant current of 5 mA to 90 mA to drive LEDs. The current can be externally adjusted through a resistor, and LED brightness can be adjusted from 0% to 100% via the OE pin. The device supports a high clock frequency of 30 MHz, making it suitable for high data rate transmission, and includes thermal shutdown protection for overtemperature events. It is available in four different packages: QSOP24, SO-24, TSSOP-24, and HTSSOP-24 (with exposed pad).
