CAT4016
16-Channel Constant Current LED Driver
FEATURES
DESCRIPTION
16 Constant current-sink channels
Serial interface up to 25MHz clock frequency
3V to 5.5V logic supply
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.
LED current range from 2mA to 100mA
LED current set by external RSET resistor
300mV LED dropout at 30mA
Thermal shutdown protection
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.
Available in RoHS-compliant 24-lead SOIC,
TSSOP, QSOP, and 4 x 4mm TQFN packages
APPLICATION
Billboard Display
Marquee Display
Instrument Display
General Purpose Display
Thermal shutdown protection is incorporated in the
device to disable the LED outputs if the die
temperature exceeds a set limit.
For Ordering Information details, see page 14.
The device is available in the 24-lead SOIC, TSSOP,
QSOP and the compact TQFN 4 x 4mm packages.

PIN FUNCTION
GND is the ground reference pin for the device. This
pin must be connected to the ground plane on the
PCB.
BLANK is the LED channel enable and disable input
pin. When low, LEDs are enabled according to the
output latch register content. When high, all LEDs are
off, while preserving the data in the output latch
register.
SIN is the serial data input. Data is loaded into the
internal register on each rising edge of CLK.
SOUT is the serial data output of the 16-bit serial shift
register. This pin is used to cascade several devices
on the serial bus. The SOUT pin is then connected to
the SIN input of the next device on the serial bus to
cascade.
CLK is the serial clock input. On each rising CLK
edge, data is transferred from SIN to the internal 16-
bit serial shift register.
LATCH is the latch data input. On the rising edge of
LATCH, data is loaded from the 16-bit serial shift
register into the output register latch. On the falling
edge, this data is latched in the output register and
isolated from the state of the serial shift register.
RSET is the LED current setting pin. A resistor is
connected between this pin and ground. Each LED
channel current is set to 50 times the current pulled
out of the pin. The RSET pin voltage is regulated to
1.2V.
LED1 - LED16 are the LED current sink channels.
These pins are connected to the LED cathodes. The
current sinks drive the LEDs with a current equal to 50
times RSET pin current. For the LED sink to operate
correctly, the voltage on the LED pin must be above
0.4V.
VDD is the positive supply pin voltage for the entire
device. A small 1µF ceramic is recommended close
to pin.

BASIC OPERATION
The CAT4016 uses 16 tightly matched current sinks to
accurately regulate the LED current in each channel.
The external resistor, RSET, is used to set the LED
Pull-up and pull-down resistors are internally provided
to set the state of the BLANK and LATCH pins to the
off-state when not externally driven.

.
SERIAL INTERFACE
1.2
A high-speed serial 4-wire interface is provided to
program the state of each LED on or off. The
interface contains a 16-bit serial to parallel shift
LEDcurrent = 50×
RSET
Tight current regulation for all channels is possible
over a wide range of input and LED voltages due to
independent current sensing circuitry on each
channel. The LED channels have a maximum dropout
of 0.4V for most current and supply voltage
conditions. This helps improve the heat dissipation
and efficiency of the LED driver.
register (S1-S16) and
a 16-bit latch (L1-L16).
Programming the serial to parallel register is
accomplished via SIN and CLK input pins. On each
rising edge of the CLK signal, the data from SIN is
moved through the shift register serially. Data is also
moved out of SOUT which can be connected to a next
device if programming more then one device on the
same interface.
Upon power-up, an under-voltage lockout circuit
clears all latches and shift registers and sets all
outputs to off. Once the under-voltage lockout
threshold has been reached the device can be
programmed.
On the rising edge of LATCH, the data contents of the
serial to parallel shift register is reflected in the
latches. On the falling edge of LATCH, the state of the
serial to parallel register at that particular time is
saved in the latches and does not change irrespective
of the contents of the serial to parallel register.
The driver delays the activation of each consecutive
LED output channel by 17ns (typical). Relative to
LED1, LED2 is delayed by 17ns, LED3 by 34ns and
LED16 by 250ns typical. The delay is introduced when
LATCH is activated. The delay minimizes the inrush
current on the LED supply by staggering the turn on
and off current spikes over a period of time and
therefore allowing usage of smaller bypass capacitors.
BLANK is used to disable all LEDs (turn off)
simultaneously while maintaining the same data in the
latch register. When low, the LED outputs reflect the
data in the latches. When high, all outputs are high
impedance (zero current).
