Electronic Fans News: The world's largest manufacturer of analog circuit technology components, the world's leading semiconductor multinational company Texas Instruments (TI) held a TI motor drive and control conference on April 17, 2012 at the Crowne Plaza Hotel in Venice, Shenzhen. Mr. Li Zhilin, China Marketing Manager of Semiconductor Division of Texas Instruments Semiconductor Technology (Shanghai) Co., Ltd. explained in detail the development of TI in the field of motor drive and control and the release of the latest DRV8x series motor control chips.
TI China Marketing Manager Li Zhilin
Nowadays, motors are everywhere, and they are inseparable from life and industrial applications. For example, range hoods, microwave ovens, vacuum cleaners, air conditioners, refrigerators, in addition, computers, DVDs, etc. have motors; industrial transmission equipment, automated production lines, textile machinery, etc. use motors. The motors used in automobiles are even more diverse.
With more than 20 years of experience in the field of motors, TI continuously improves the efficiency of motors through embedded intelligent technology.
Embedded intelligent technology can also reduce costs and accelerate the time to market, and it is accelerating the market's transformation from brushed motors to brushless motors. TI continuously improves the efficiency of the motor through advanced control algorithms and digital speed and torque control loop research.
Li Zhilin pointed out: The development direction of TI motor drive and control chips is to provide customers with the most easy-to-use, easy to operate, and highly reliable products. Take the TI DRV8x series as an example, its reliability is relatively high, TI concentrates all protection functions in the chip, greatly reducing the board area, and the response time is short, can be in the temperature range of -40 ℃ -85 ℃ Work within. TI's perfect motor control solution solves the problems of user development and use.

At this meeting, Li Zhilin mainly explained the newest DRV8818, DRV3334, DRV3335, DRV3336 from Texas Instruments (TI).
DRV8818 is a 2.5A stepper motor driver. Because the product integrates peripheral devices, greatly reducing board space, its Low RDSON FETs 0.37-Ω (HS + LS); while most competitors are around 0.5 -Ω, showing TI's advantage in motor control. DRV8818 supports fast decay, slow decay, mixed decay, has configurable motor performance, and improves the stability and performance of the system.
