CAT4016_15 Datasheet, PDF (1/14 Pages) ON Semiconductor – 16-Channel Constant Current LED Driver

CAT4016, CAV4016
16-Channel Constant
Current LED Driver
Description
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 0.4 V (for 2 to
100 mA LED current) allows for more power efficient designs.
A high−speed 4−wire serial interface of up to 25 MHz 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. The
device 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 the device to
disable the LED outputs if the die temperature exceeds a set limit.
The device is available in the 24−lead SOIC, TSSOP and the
compact TQFN 4 x 4 mm packages.
