ROHM, a world-renowned semiconductor manufacturer, has developed the reference frame " BM620xFS -EVK-001 Series" for evaluation of high-voltage fan motor drivers, which can realize the frequency conversion of household air conditioners and ceiling fans, etc., extremely simply and efficiently. .
So far, the cumulative shipment of ROHM high-efficiency motor controllers has reached more than 50 million. The power components have also developed the unique PrestoMOS*1. The product and technical strength have been highly praised in the motor application market. Last year, we developed a 600V high-voltage fan motor driver " BM620xFS series" that combines the technical advantages of these two products, and has been promoted globally.
The latest evaluation reference board " BM620xFS -EVK-001 Series" is equipped with the "BM620xFS Series" high-voltage fan motor driver for mass production. The power-on mode of the controller is divided into 120 degrees, 150 degrees, and 180 degrees. Three kinds of drives, the output current of the driver is divided into 1.5A, 2.5A, and can immediately start to evaluate a total of six products that meet a wide range of needs.
The BM620xFS-EVK-001 series has been online since November 2016 at Digi-Key Electronics and Mouser Electronics. In addition, various documents such as the Getting Started Guide required to use the evaluation reference board can be downloaded from the ROHM website.
In the future, ROHM will combine the advantages of high-efficiency control ICs and low-loss power components to continue to provide power solutions that help save energy worldwide.
It is understood that nearly 50% of the global electricity demand is used for motor drive. With the popularity of air conditioners in emerging countries, the global power situation is grim year after year. Globally, the penetration rate of home appliances equipped with a frequency conversion function that contributes to energy saving is still low, and the significant role of a fan motor driver that realizes frequency conversion has become increasingly prominent.
The data required to import the reference board has been published on the ROHM website.

1. Simultaneously achieve the industry's highest level of 600V withstand voltage and efficient drive
The motor controller that has achieved great results is built into the ROHM's unique 600V voltage-resistant PrestoMOS driver for integrated packaging. Therefore, it is extremely easy to realize a high-efficiency sine wave motor that can only be realized in two packages in the past. Compared with a fan motor driver (500V withstand voltage) equipped with a common MOSFET, it can maximize the performance of PrestoMOS and achieve higher withstand voltage and lower loss, and can be assured in countries and regions where power infrastructure is unstable. use.
2. The industry's smallest level of small surface mount package
The controller, 600V withstand voltage PrestoMOS, gate driver, bootstrap diode, etc. are all integrated in a small surface mount package (length 22.0mmx width 14.1mmx height 2.4mm). Achieve the industry's smallest level of size in equivalent products.
3. The product lineup is rich and can meet a wide range of needs.
The controller includes three common energization modes: 120-degree energization (rectangular wave), 150-degree energization (wide-angle), and 180-degree energization (sine wave). The output current includes 1.5A and 2.5A, and a total of 6 products can meet the requirements. A wide range of market needs.
In addition, these products are all in the same package, the same pin configuration, and also contribute to the universal design of the motor PCB board.
Very suitable for
â—‡Home Air Conditioner/Outdoor Fan â—‡ Ceiling Fan â—‡ Air Purifier
â—‡ heat pump â—‡ DC fan â—‡ dishwasher â—‡ washer dryer
Wait for white motor fan motor and pump motor.
*1) PrestoMOS
Presto says "very fast," a musical term derived from Italian. It is one of ROHM's original power MOSFETs that are ideal for power-integrated inverters. It achieves fast on-recovery of low on-resistance and internal diodes compared to general products.
