STP16CPP05 is a low voltage, low current 16-bit constant current LED sink driver, featuring 16 constant current output channels, adjustable output current through external resistor, output current range of 3-40 mA, serial data in/parallel data out, etc.
The STP16CPP05 is a monolithic, low-voltage, low-current power 16-bit shift register designed for LED panel displays. It contains a 16-bit serial-in, parallel-out shift register that feeds a 16-bit, D-type storage register. The output stage provides sixteen regulated current sources to drive LEDs with constant current ranging from 3 mA to 40 mA.
The device features adjustable output current through an external resistor and supports supply voltages of 3.3 V or 5 V. With a maximum clock frequency of 30 MHz and Schmitt-trigger inputs, it is suitable for high data rate transmission and interfacing with microcontrollers. The output current setup time is 40 ns typical, improving system performance.
