1. Bipolar stepper motor drive and controller
The AMIS-3062x series AMIS-30623 developed by ON Semiconductor is the drive and controller for bipolar stepper motors in highly efficient electromechanical actuators. This product embeds a dedicated finite state machine and a local interconnect network (LIN) instruction set tailored to the requirements of advanced headlamp system (AFS) systems. The device integrates non-sensing control detection to increase reliability, reduce component count and board space, and reduce product cost. Designed for remote and multi-axis positioning applications, the AMIS-30623 allows designers of non-sensing control detection to easily perform precise positioning and calibration and semi-closed loop operations.
2. Precise dynamic control of stepper motor
As stepper motors appear in more and more applications, designers continue to pursue high-precision positioning. In addition, its high energy efficiency, high performance and shrinking size make it attractive for textile machines, robots, CNC milling machines and other equipment. ON Semiconductor's AMIS-305xx series is used in ASSPs that require precise dynamic control of stepper motor systems. It provides variable motor current control with an SPI interface for precise dynamic control.
3. Other motor drive control solutions
ON Semiconductor's NCV770x series drivers are also commonly used to drive air lobes in HVAC electronic control units. This family of half-bridge drivers offers a cost-effective solution for driving multiple brushed DCs in series or parallel, while also meeting the latest automotive standards for reliability, diagnostics, battery-powered transients, etc. over the life cycle.
to sum up
Energy efficiency is a general trend, and motor drives are also becoming a high-volume general-purpose product, and reducing the cost per motor drive and reducing the size of the solution are the main drivers. The market will gain a dynamic balance between efficient control and cost.
Based on strategic priorities and understanding of system requirements, especially for customer needs, ON Semiconductor uses a customized approach to provide customers with different solutions from ASSP to customer-specific integrated circuits (ASICs). These solutions will help motor application designers in the consumer electronics, industrial control and automotive electronics industries in the Chinese market achieve higher efficiency, longer life and better fault control, enabling the motor to be miniaturized and efficient. Low noise and higher reliability.
