THine releases an industry-first motor driver with LVDS input/output


2016/03/29

- Achieving superior noise tolerance and simple wiring design in high-speed long-distance data transmission -
 
TOKYO (March 29, 2016) – THine Electronics, Inc. (TSE/JASDAQ: 6769), the global leader in high-speed serial interface and provider of mixed-signal LSI today announced an industry-first* motor driver product, THM3561, with input/output of LVDS or Low Voltage Differential Signaling. THM3561 will be available in the second quarter, 2016.
 
The new motor driver product, allowing differential signaling by LVDS input/output, is developed with THine’s accumulated technology and know-how in high-speed serial interface. The new feature with LVDS input/output achieves superior noise tolerance and high-speed data transmission for long distance. Since THine has LED driver line-ups also with LVDS input/output, this brand-new motor driver can be used jointly with THine’s LED drivers by cascade connection or multi-drop connection. Joint use of THine’s motor driver and LED driver both with LVDS input/output enables to simplify internal interface of equipments and application systems.
 
Moreover, plural THM3561 products can be connected only by two pair cables and every control can be achieved. This feature also contributes to reduce the number of cables, wiring spaces, and costs, accelerating time-to-markets. For example, a cascade connection of THM3561 products in every 3 meters allows complicated controls of 30 motors with long-distance data transmission for approximately 100 meters only by two pair cables. The anticipated application is large machine tools, factory automation and robotics, large motor control systems for long-distance, motor drivers of robotics or humanoid robots such as those with 30 finger-joints of both hands.
THM3561 also has serial interface to transmit sensor output signals of position detection to controllers. Spread of Internet of Things or IoT brings numerous sensors and the new product THM3561 can drive motors according to the output signal from sensors, reducing the parts counts drastically and simplifying the systems.
 
In addition to driving motors, THM3561 can drive 4-channel electromechanical solenoids that move iron cores and convert electrical current into fast straight-line movement with greater force and quick response. THine’s new solution with THM3561 enables to reduce the total number of cables for driving solenoids. It can be applied to various markets of consumer electronics, document processing, electromagnetic switches and relays, automatic vending machines, and other industrial equipments.
 
THine plans to develop new motor drivers and add the lineups according to the markets’ requests, starting from the THM3561.
