TOKYO (April 22, 2015) -- THine Electronics, Inc. (JASDAQ: 6769), the global leader in high-speed serial
interface and provider of mixed-signal LSI, today announced its mass production of new LED drivers with
LVDS interface, THL3512 and THL3514.
Since THine has accumulated know-how in serial interface technology and power management technology,
these new products have the serial interface of 2-pair LVDS lines (clock and data) and achieve higher-level
noise tolerance, high-speed and long-distance transmission. THL3512 / 3514 can reduce the possibility of an
incorrect action or improper LED lighting, expanding the transmitting distance. In addition, these new LED
drivers have controlling function of gradation and are suitable for equipments with full-color LEDs such as
amusement equipments, LED backlights, LED displays, LED decorative illumination, LED billboard
lighting, and digital signage applications.
THL3512 has 24-channel open drain outputs. THL3514 has 24-channel constant current sink outputs and its
constant current values for three output groups are determined by external resisters. Each of these new LED
drivers has an embedded oscillator and PWM controller that individually generates 256-step brightness set
by the dedicated registers for each channel. The LVDS allowing cascaded and multi-drop 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.
