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 D-

type storage register. In the output stage, four

regulated current sources were designed to

provide 80-500mA constant current to drive the

high powered LEDs.

(Exposed pad)

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.
