Reference boards for high voltage fan motor drivers

ROHM reference boards designed to evaluate its high voltage fan motor drivers are now available. They achieve greater efficiency and simplify inverter configuration in home appliances such as ceiling fans and ACs. The company’s 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, they 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 six reference boards, each integrating one of the six models in their lineup of high voltage fan motor drivers, which is offered in three different drive types (120, 150, 180 degrees) and two 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.
