Description
The STP04CM596 is a high-power LED Driver and 4-bit shift register designed for PowerLED applications. The STP04CM596 contains a 4-bit serial IN, parallel OUT shift register that feeds a 4-bit Dtype storage register. In the output stage, four regulated current sources were designed to provide 80-500mA constant current to drive the high powered LEDs. The STP04CM596 guarantees 16V output driving capability, allowing users to connect more LEDs in series. The high clock frequency, 25 MHz, also satisfies the system requirements which include high volume data transmission. The STP04CM596 is well suited for very high brightness displays and special lighting applications. The STP04CM596 is offered in DIP-14, SO-14 and TSSOP16 Exposed Pad packages.
