The CAT4008Y-T2 from On Semiconductor is an 8-channel constant current LED driver suitable for billboard, marquee, and general purpose display applications. It allows for individual channel control via a high-speed 4-wire serial interface operating up to 25 MHz.
LED channel currents are programmed together using an external RSET resistor, with a range from 2 mA to 100 mA. The device supports low output voltage operation, down to 0.4 V for 2 to 100 mA LED current, enabling more power-efficient designs. A blanking control pin is included to disable all channels independently of the interface.
This LED driver incorporates thermal shutdown protection to safeguard the device if the die temperature exceeds a set limit. It operates with a logic supply voltage between 3 V and 5.5 V. The CAT4008Y-T2 is available in a 16-lead TSSOP package, designed for surface mounting.
Key features include 8 constant current-sink channels, a serial interface up to 25 MHz clock frequency, and a 3 V to 5.5 V logic supply. The LED current range is from 2 mA to 100 mA, set by an external RSET resistor. It offers 300 mV LED dropout at 30 mA and includes thermal shutdown protection.
