The motor drive is playing an important role behind the numerous machines that are easily accessible. The huge application market has attracted manufacturers to hang around. Recently, TI's China market development of high-performance analog products business development manager Xin Benwei said at the event, "most of TI's products are widely used in hard drives, optical drives, inkjet printers, automotive, industrial and other aspects, in 2010 we will All the parts that make the motor are put together, and the Motor Drive Division is established to fully enter the mass market." Xinbenwei said that with the continuous development of technology, the market has put forward new requirements for motor drive - safety, energy efficiency, intelligent algorithms, and TI has actively responded to challenges with its rich product line and nearly 20 years of successful experience. to satisfy the market's needs. TI motor driver series The road to integration has Blue Ocean TI to create a high security solution Xin Benwei said, "When doing motor drive, TI also has a lot of considerations. Is it to do this separation or integration in the market? Finally, we have unified an idea that we have to do a highly integrated solution that will drive MOS tubes, protection circuits, control switches, and algorithms are all brought together." The benefits of this are also obvious: 1, effectively reduce the PCB size, reduce the BOM; 2, high integration can effectively improve reliability and security; 3, no need for discrete design. TI's integrated motor products offer significant volume advantages. “For motors, especially for industrial or automotive applications, the reliability requirements are very high, so we have integrated the protection circuits that we can basically see on the market throughout the design. Some of the costs have been added, but the safety of the products will be very high. For the more common hair curlers in daily life, there have been customers who did not perform breakdown protection, and as a result, the motor was deadlocked after the breakdown, although the current would not be transmitted to the hands. But the hair is rolled up on it and can't be taken." Xin Benwei said. TI's circuit protection includes overcurrent/short circuit protection, overtemperature protection, undervoltage lockout, and breakdown protection. Overcurrent protection : Xinbenwei pointed out that many people think that as a protection between coils, the power supply is short-circuited, but there is actually current, and TI has a short circuit between ground, power supply and coil. Stream protection. In addition, TI also has a single tube protection. “Each power transistor actually needs to be protected separately. The entire protection circuit of most discrete devices is only the total level. When you burn a second MOSFET after a MOSFET is burned, it will be changed after the current is changed. Protection, but it was already late. We are adding a so-called current-limiting and voltage-limiting protection to each power tube on every gate-level circuit. This is very important." Short-circuit protection : In the case of TI DRV88xx, when the normal current is short-circuited, it will return to the loop current of 9A in 400 nanoseconds, and then react in real time around 3 microseconds to avoid device burnout. "If it exceeds 50 microseconds, the protection loses its meaning, so the shutdown must be within 10-15 microseconds." Overheat protection ( thermal shutdown ): Thermal shutdown design of the board temperature, motor temperature, IC temperature, etc., so there will be many thermistors to monitor to ensure normal operation. "TI will increase the pre-judgment in some products. Generally, the temperature will be lower than the thermal shutdown threshold by about 20-30 degrees."
