Renesas Electronics launches RAA306012 sensorless motor driver IC family

Renesas Electronics announced on December 6 that it has launched a series of sensorless motor driver IC products suitable for brushless DC (BLDC) motor applications. This series of products adopts new patent-pending technology from Renesas. This breakthrough technology enables the motor to achieve full torque at zero speed without sensors, creating an industry first. The new family of motor driver ICs provides Renesas customers the ability to design sensorless BLDC motor systems with greater horsepower and speed while reducing power consumption, improving reliability, and cutting costs by reducing the number of components required. and board space.

Renesas has released three new motor driver ICs using new technologies. Among them, RAA306012 is an independent 65V, 3-phase smart driver that can be paired with Renesas or various other MCUs; RAJ306101 integrates Renesas RX13T 32-bit MCU and RAA306012 in a single package, thereby reducing circuit board space and cost , improved reliability; RAJ306102 integrates Renesas RL78/G1F 16-bit MCU with RAA306012, bringing similar integration advantages.

The family’s ability to achieve full torque at zero speed without sensors is a result of two Renesas innovations: Enhanced Inductive Sensing (EIS) for stable position detection when the motor comes to a complete stop; When running at extremely low speeds, the motor rotor position recognition (MRI) method is used. At higher speeds, new motor driver ICs take a traditional approach. Both the new EIS and MRI algorithms incorporate cutting-edge patent-pending technology developed by Renesas.

Davin Lee, vice president of Renesas' Advanced Analog Division, said: "The new sensorless design of the motor driver IC offers many advantages in terms of cost, space, power consumption and reliability. Now, our customers can system. This industry first allows Renesas to combine its technological prowess with deep application knowledge to create products that meet clear market needs."

This new series of sensorless motor driver IC products also have rich protection functions, including over-current protection, over-voltage protection, under-voltage protection, over-temperature protection, etc., which improves the safety and stability of the system. In addition, these products also support a variety of motor control algorithms, including trapezoidal control, sine control and FOC (Field Oriented Control), etc., to meet the needs of different application scenarios.

Renesas Electronics' new generation sensorless motor driver IC products have been successfully used in vacuum cleaners, leaf blowers and other products, forming a rich "successful product portfolio." These products are based on compatible and seamlessly working devices with technically proven system architectures, resulting in optimized low-risk designs and faster time to market. Renesas has currently launched more than 400 "successful product portfolios" that enable customers to accelerate the design process and bring products to market faster.

Renesas Electronics' new generation of sensorless motor driver IC products not only make important contributions in reducing electromagnetic radiation, but also make significant progress in performance, safety and product portfolio, providing customers with more choices and faster time to market.
