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 0.4V
(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.
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,
QSOP and the compact TQFN 4 x 4mm packages.
