16-BIT CONSTANT CURRENT LED DRIVER
DESCRIPTION
SC6616 is a constant current LED driver. It includes shift register,
data latches, constant current drivers and etc. There are
16-channel constant current output, with 1-35mA current available
at each channel. This constant current can be set through an
external resistor.

SC6616_Datasheet
FUNCTION DESCRIPTION
For LED display application, the serial data can be shifted from SDI to internal 16-bit shift register via DCLK riding
edge and shifted out at SDO. And the SDO of previous SC6616 can be connected to SDI of the next SC6616 for
cascade connection. The data in shift register can be written in data latch when LATCH is high, and data is latched
when LATCH is low. The data in data latch is for controlling on/off of 16-channel constant current source. The constant
current source is controlled by data latch when OE is low, and constant current source is off when OE is high, with
high impedance output. The current of constant current source can be set through an external resistor connected to
R-EXT.
Notes: there is only one ground pin shared as analog/digital/power ground. It is recommenced to adopting the routing
with minimum inductance to reduce conversion noise caused by input signal and fault caused by output current. The
proper output voltage is needed for better constant current output, and the minimum output voltage can be obtained
according to the electrical characteristics. To avoid noise on current, the resistor should be placed near pin R-EXT with
shortest routing from GND of resistor to PIN1 of SC6616.
Time sequence DIAGRAM
Note: the data in shift register is shifted by DCLK rising edge.
The data in shift register is written in data latch when LATCH is high, and data is latched when LATCH is low.
——
The output is enabled when OE is low.
——
When OE is high, output is off, and the status is high impedance.
