The CAT4008V-T1 from ON Semiconductor is an 8-channel constant current sink driver suitable for LED billboard, marquee, instrument, and general-purpose display applications. It allows LED channel currents to be programmed together using an external RSET resistor, with a range from 2 mA to 100 mA. The device operates with a logic supply voltage between 3 V and 5.5 V and supports a high-speed 4-wire serial interface up to 25 MHz.
Key features include low output voltage operation down to 0.4 V for efficient designs, and a blanking control pin for independent channel disabling. Thermal shutdown protection is integrated to prevent damage from overheating. The CAT4008V-T1 is available in a 16-SOIC package and is RoHS compliant.
This driver is ideal for applications requiring precise control over multiple LED channels, such as large displays and illuminated signage. Its serial interface simplifies cascading multiple devices for larger channel counts.
