DESCRIPTIONS
The THL3504 is an LED driver with 24 channel constant
current sink outputs. The constant current values for
three output groups are determined by external resistors.
The embedded oscillator and PWM controller
individually generates 256-step brightness set by the
dedicated registers for each channel.
The serial interface of 2-pair LVDS lines (clock and
data) features high-level noise tolerance, high-speed, and
long-distance transmission.
The LVDS allowing cascaded and multidrop connection
offers the maximum flexibility for designers to place and
connect LED drivers.
The simple and one-way communication protocol is
easily-controlled and requires less CPU resources.
