STP16CPC05 Low voltage 16-bit constant current LED sink driver with balanced output rise/fall time Datasheet - production data Description The STP16CPC05 is a monolithic, low voltage, low current power 16-bit shift register designed for LED panel displays. The STP16CPC05 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 mA to 100 mA constant current to drive the LEDs. The STP16CPC05 s output stage is designed to optimize the turn-on and turn-off time, typically 100 nS. The balanced turning ON/OFF improves the system performances reducing the bypass Features capacitance in applications where parasitic inductance generate ringing or noise in the Low voltage power supply down to 3 V system. The LEDs brightness can be controlled 16 constant current output channels by using an external resistor to adjust the Adjustable output current through external STP16CPC05 output current. The STP16CPC05 resistor guarantees a 20 V output driving capability, Serial data IN/parallel data OUT allowing users to connect more LEDs in series. Can be driven by a 3.3 V microcontroller The high clock frequency, 30 MHz, makes the Output current: 5-100 mA device suitable for high data rate transmission. Max clock frequency 30 MHz The 3.3 V voltage supply is useful in applications ESD protection 2.5 kV HBM, 200 V MM that interface with a 3.3 V microcontroller.
