The STP16CPC26 is a monolithic, low voltage, 16-bit constant current LED sink driver, with 16 constant current output channels, adjustable output current through external resistor, output current: 5mA to 90mA, ±1% typical current accuracy bit to bit, max clock frequency: 30MHz, 20V current generators rated voltage, 5V power supply, thermal shutdown for overtemperature protection.
The STP16CPC26 is a monolithic, low voltage, 16-bit constant current LED sink driver designed for video display panel LED drivers and special lighting applications. The device contains a 16-bit shift register and data latches that convert serial input data into parallel output format. Sixteen regulated current generators provide a constant current of 5 mA to 90 mA to drive LEDs, with the current externally adjustable through a resistor. LED brightness can be adjusted from 0% to 100% via the OE pin.
The STP16CPC26 guarantees a 20 V driving capability, allowing users to connect more LEDs in series to each current source. Its high 30 MHz clock frequency makes the device suitable for high data rate transmission. Additionally, the device features thermal shutdown protection at 170°C with about 15°C hysteresis to ensure protection from overtemperature events. It is available in four different packages: QSOP-24, SO-24, TSSOP-24, and HTSSOP-24 (with exposed pad).
