CAT4016

The CAT4016 is a 16 channel constant current driver for LED billboard and other general display applications. LED channel currents are programmed together via an external RSET resistor. Low output voltage operation on the LED channels as low as 0.4V (for 2 to 100mA LED current) allows for more power efficient designs.

A high-speed 4-wire serial interface of up to 25MHz clock frequency controls each individual channel using a shift register and latch configuration. A serial output data pin (SOUT) allows multiple devices to be cascaded and programmed via one serial interface. CAT4016 also includes a blanking control pin (BLANK) that can be used to disable all channels independently of the interface.

Thermal shutdown protection is incorporated in CAT4016 to disable the LED outputs if the die temperature exceeds a set limit.

CAT4016 is available in the 24-lead SOIC, TSSOP, QSOP and the compact TQFN 4 x 4mm packages
