The CAT4008W-T2 is an 8-channel constant current LED driver designed for applications such as billboard and general display lighting. It operates with a low output voltage as low as 0.4 V, supporting LED currents from 2 mA to 100 mA, which enhances power efficiency. The device features a high-speed 4-wire serial interface capable of clock frequencies up to 25 MHz, allowing for individual channel control through a shift register and latch configuration. It also includes a serial output data pin (SOUT) for cascading multiple devices. Thermal shutdown protection is integrated to disable LED outputs if the die temperature exceeds a specified limit, ensuring safe operation. The CAT4008W-T2 is available in TSSOP and SOIC packages and is compliant with RoHS standards, being Pb-free and halogen-free. It operates within a supply voltage range of 3 V to 5.5 V and is suitable for various display applications, including marquee and instrument displays.
