The ST motor control chip makes the automation system smaller and runs smoother and quieter

     STMicroelectronics introduces the latest electronic innovations to make precision motor control for high-precision robots more advanced.Advanced laboratory automation systems featuring precision and space savings are helping medical centers cut clinical trial costs, shorten lab report turnaround times, and provide high-quality care to more patients, while industrial robots such as 3D printers have dramatically increased accuracy and throughput in recent years. 3D printers can print complex shapes quickly and accurately, and are becoming more affordable for consumer and professional products from prototyping to manufacturing development processes.

     St's STSPIN820IC enables the next generation of stepper motor-based robots to run smoother, quieter, smaller, more accurate and with lower power consumption. With its high-speed input and precise microstep algorithm, the chip can rotate the motor rotor by a very small number of degrees, allowing the print head to move faster than 500mm/s, its submicron accuracy enables very fast printing, very smooth print surfaces, and control extremely precise movements, such as sample loading, encapsulation/opening, and access in next-generation clinical automation systems. With this driver chip, other medical devices, such as platform-arm processing systems, fluid pumps, blood analyzers, and ventilators, can become quieter, more compact, and more economical.

     Size only 4mmx4mm, built-in motor control required control algorithm and protection of complete power devices (rated 45V and 500m2RDS(ON)), the chip is the world's smallest all-in-one high-precision motor controller, automation equipment manufacturers can directly put it on the control board, Complete system design requires very few additional components, so this motor drive chip saves board space and improves system reliability.

     DomenicoArrigo, general manager of ST's Industrial and Power Conversion Products division, said: "The STSPIN820 helps innovators in the field of precision automation control to continuously improve their products. In addition, the high precision, small size and low power consumption can also help other equipment manufacturers simplify the design of high-precision motor control.
