Product Summary

ROHM has been providing motor drivers for various applications for over 50 years. ROHM's single-phase brushless DC motor drivers are ideal for fan motors, etc., as they support various drive methods and control technologies required for quietness and high efficiency. We have a wide lineup including voltage and current.

Product features

charge pumpless

▪ Charge pump capacitor (high voltage, high capacity, expensive) not required
▪ Low noise design that does not generate high frequency noise because no charge pump is required

Wide lineup

▪Pin compatible: excitation mode, output current (1, 2, 3A)
Built-in Over-Current Protection (OCP) protection circuit

Various problems (especially heat problems) that occur after the customer's board design can be resolved by remounting the IC.
