DESCRIPTION
The TLC5930 is a constant-current sink driver
with an adjustable current value, and 1024 gray
scale display that uses pulse width control. The
output current is 0.2 mA to 40 mA with 12 bits of
RGBx4. The maximum current value of the
constant-current output can be set by one external
resistor.
The TLC5930 includes three kinds of brightness
adjustment functions: one adjusts the plane
brightness between devices, changing the current
values of all outputs uniformly. The second adjusts
the frequency division to controls overall panel
brightness, and the third adjusts the dot correction
per LED, changing the current values of
independent output.
The TLC5930 also includes color–tone correction
function for correcting color per dot (pixel) and
OVM function for constant-current output
terminals used for LED failure detection.
Other features include the thermal error flag
(TEF). The active wire-check (AWC) to check the
communication between the controller and the
device. The LED leakage-detect (LKD) to detect
the reverse leakage on the LED. The GCLK error
flag (GEF) and the HSYNC error flag (HEF) by
monitoring the gray-scale clock count, and the
dual source gray-scale clock (DSG) function to
switch the gray-scale clock to the external input
clock or to switch the internally-generated clock.
The TLC5930 requires three signals for standard
operation: data input and gray-scale clock. Only
three-signal line and 24-pin HTSSOP package
reduce board area and total cost.

Stresses beyond those listed under absolute maximum ratingsmay cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under recommended operating conditionsis not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. All voltages values are with respsect to GND terminal.
2. At operating temperature range over 25°C, dependent on derating factor of 41 mW/°C.
