STP16CPS05 Low Voltage 16-Bit Constant Current LED Sink Driver Datasheet
The STP16CPS05 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 from 5 mA to 100 mA.
The device features an auto power-saving function that minimizes quiescent current if no active data is detected on the latches. It can be driven by a 3.3 V microcontroller and guarantees a 20 V output driving capability, allowing users to connect more LEDs in series. The output current setup time is 40 ns (typ), improving system performance.
