STP04CM596 4-Bit constant current for power-LED LED sink driver General features ■ ■ ■ ■ ■ ■ ■ 4 constant current output channels Adjustable output current through one external resistor Serial data IN/parallel data OUT Serial OUT change state on the failing edges of clock Four outputs current: 80-500mA 25MHz clock frequency Available in high thermal TSSOP exposed pad. TSSOP16 (Exposed pad) Dip-14 SO-14 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.

When the LE terminal is at a High level, the latch circuit holds the data it passes from the input to the output. When the OE terminal is at a Low level, the output terminals OUT0 to OUT3 respond to the data, either ON or OFF. When the OE terminal is at a High level, it switches off all the data on the output terminal. 11/24 Timing diagrams Figure 8. Clock, serial-IN, serial-OUT STP04CM596 12/24 STP04CM596 Figure 9.
