Melexis is the first in the world to introduce 60W single coil sensorless BLDC driver chips

     Melexis announced the MLX90416, a 24V/60W sensorless single-coil BLDC driver chip designed for motor, fan and pump applications in the consumer electronics and industrial sectors. At present, many consumer electronic devices and industrial applications, such as electric fans, air purifiers, vacuum cleaners, water pumps and ventilation facilities, generally use a combination of three-phase BLDC motors and driver chips or AC induction motors. However, both solutions have obvious limitations: three-phase BLDC motors are costly and complex; Ac induction motors lack energy efficiency and advanced features.

     The MLX90416 provides an efficient and cost-effective solution to these pain points, helping to simplify the motor design and manufacturing process. The product is based on Melai core's "No-Hall" technology, which does not require feedback sensors, and adopts advanced integrated drive and feedback algorithm (BEMF) to achieve quiet and non-vibration operation effect comparable to that of three-phase drive chips.

     This technological innovation allows designers to flexibly place the BLDC driver chip outside the fan body, regardless of the location of the magnet. This shift makes the design more flexible - the same PCB can be easily configured with fans of different diameters without the need for redesign. In this way, the MLX90416 not only significantly reduces the complexity of the manufacturing process, but also significantly reduces the design effort and bill of Materials (BoM) cost.

     The MLX90416 has the advantage of high integration and can drive a 24V fan with a maximum operating power of 60W. The chip has plug-and-play, code-free and other convenience, and users can easily configure it through an intuitive GUI to achieve rapid deployment and adjustment in various application scenarios. In addition, the MLX90416 supports forward and reverse rotation operation and features an advanced 8-point configurable speed curve, which allows for precise adjustment of fan performance to effectively address resonance and vibration issues, beyond the limitations of fixed curve solutions.

     As a fully integrated solution, the MLX90416 offers increased reliability compared to separate sensorless solutions, while significantly reducing the design burden and packaging considerations. The chip not only supports PWM and FM control, but also is compatible with I2C protocol, showing its versatility. The MLX90416 is used in a wide range of applications, including white goods and consumer electronics such as fans, air fryers, ovens and vacuum cleaners, as well as industrial systems such as cooling fans and water pumps. Regardless of the application scenario, the MLX90416 helps to reduce the cost of the product, extend the service life and reduce component consumption, promoting product sustainability.

     "Melaixin has more than three decades of expertise in single-coil product development and has been at the forefront of the industry since the successful launch of our first product in 1993," "The MLX90416 not only creates substantial value for our customers by reducing development burdens and costs, but also significantly increases the level of intelligence and digitalization of their designs, ultimately benefiting the end-users," said Ou Xianhong, regional Marketing Manager at Melaixin.
