Description
The STP16CP596 is a monolithic, low voltage, low current power 16-bit shift register designed for LED panel displays. The STP16CP596 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 were designed to provide 3-50mA constant current to drive the LEDs. Compared with the STPIC6C595, the device provides great flexibility and improved performance in LED panel system design. Users can adjust the STP16CP596 output current with an external resistor, controlling the LEDs' light intensity. The STP16CP596 guarantees a 16V output driving capability, allowing users to connect more LEDs in series. The high clock frequency (25MHz) also satisfies the high volume data transmission system requirement. The 3.3V voltage supply is useful for applications that interface any microprocessor from 3.3V. Compared with a standard TSSOP package, the TSSOP exposed pad increases heat dissipation capability by a factor of 2:5.……
