DESCRIPTION
The TLC59711 is a 12-channel, constant-current sink
driver. Each output channel has individually
adjustable currents with 65536 PWM grayscale (GS)
steps. Also, each color group can be controlled by
128 constant-current sink steps with the global
brightness control (BC) function. GS control and BC
are accessible via a two-wire signal interface. The
maximum current value for each channel is set by a
single external resistor. All constant-current outputs
are turned off when the IC is in an over-temperature
condition.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
