ROHM has recently announced the availability of reference boards designed to evaluate its high voltage fan motor drivers that achieve greater efficiency and simplify inverter configuration in home appliances such as ceiling fans and ACs.
Of the total power consumed worldwide, it has been noted that close to 50% is used to drive motors, and with the continued spread of air conditioners and other electrical appliances in emerging and developing countries this percentage is expected to only increase. On a global scale, the number of consumer devices equipped with an inverter function is low, making the role of the fan motor drive increasingly important to achieve inverter operation.
ROHM products and technologies have been well regarded in the motor application market, with over 50 million high efficiency motor controllers shipped to date and the development of innovative power devices such as PrestoMOSTM. Last year, ROHM released the BM620xFS series of 600V fan motor drivers that integrate both the PrestoMOSTM and motor controller in a single package.
The BM620xFS-EVK-001 series consists of 6 reference boards, each integrating one of the 6 models in ROHM’s BM620xFS lineup of high voltage fan motor drivers, which is offered in 3 different drive types (120°, 150°, 180°) and 2 output currents (1.5A and 2.5A) to suit a variety of set needs. This enables immediate evaluation of the ideal motor driver, speeding up development and reducing time-to-market considerably.
The boards are available online through distributors Digi-Key Electronics and Mouser Electronics. In addition, all required materials, including startup guides, user manuals, and datasheets, can be downloaded from ROHM’s website.
