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.
