STP16CPS05MTR

LED显示驱动器 Low voltage 16-bit constant current LED sink driver with auto  power saving

Description

The STP16CPS05MTR STP16CPS05 is a monolithic, low voltage,  low current power 16-bit shift register designed  for LED panel displays. The STP16CPS05MTR STP16CPS05  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 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 40 ns (typ.), 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 20 V output driving  capability, allowing users to connect more LEDs  in series. The high clock frequency, 30 MHz,  makes the device suitable for high data rate  transmission. The 3.3 V voltage supply is useful  in applications that interface with a 3.3 V  microcontroller.
