The STP16CPS05MTR is a 16-bit low-voltage constant current LED Sink Driver with auto-power saving. The monolithic low current 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. In the output stage, sixteen regulated current sources provide from 5 to 100mA constant current to drive the LEDs. The auto power shut-down and auto power-ON feature allows the device to save power without any external intervention. The output current setup time is 40ns (typical), thus improving the system performance. The LEDs brightness can be controlled by using an external resistor to adjust the STP16CPS05 output current. The STP16CPS05 guarantees a 20V output driving capability, allowing users to connect more LEDs in series. The high clock frequency, 30MHz, makes the device suitable for high data rate transmission. The 3.3V voltage supply is useful in applications that interface with a microcontroller.
