ROHM’s Cutting-Edge Motor Driver ICs for Versatile Applications

In a significant advancement for the electronics industry, ROHM Co., Ltd. has recently introduced two new motor driver ICs aimed at enhancing the functionality of brushed DC motors. The BD60210FV and BD64950EFJ are engineered to cater to a variety of applications, especially in home and office appliances like refrigerators, air conditioners, printers, and robotic vacuum cleaners.

Meeting Growing Demand

The rapid electrification of consumer and industrial products, particularly white goods, has led to a surge in demand for energy-efficient brushed DC motors. This has, in turn, created a need for versatile motor drivers that can handle multiple applications effectively while minimizing the number of necessary external components. ROHM’s latest products address these challenges head-on.

The BD60210FV is designed as a dual H-bridge motor driver operating at 20V and featuring direct PWM control. This IC is able to manage two DC brush motors simultaneously, function as a bipolar stepper motor driver, or work as a solenoid driver. By incorporating an H-bridge circuit design, the need for an additional boost circuit is eliminated, thereby streamlining both the component count and the overall design process.

Similarly, the BD64950EFJ operates at 40V with a single H-bridge setup that supports both direct and constant current PWM control. Its low on-resistance design enables efficient motor driving while significantly reducing heat generation, a common issue with traditional motor drivers.

Energy Efficiency at Its Core

Both motor drivers have been designed with energy efficiency in mind. The BD60210FV has an ultra-low standby current (as low as 0.0 microampere), which plays a crucial role in reducing power consumption during inactive periods. With the increased push for sustainable and energy-efficient solutions, these features make ROHM’s offerings not only convenient but also environmentally responsible.

Ideal for Diverse Applications

The range of applications for these new motor driver ICs is vast. In consumer electronics, these ICs are perfect for controlling the rotational aspects of refrigerators (like ice maker functionality), air conditioners (for louver operations), and printers (for carriage movements). They also facilitate operations in robotic vacuum cleaners, water heaters, rice cookers, humidifiers, and more.

In industrial settings, the BD60210FV and BD64950EFJ can control automatic doors and shutters, small conveyor systems, and even power tools. This versatility is becoming increasingly valuable as industries seek to consolidate their component needs and enhance product performance.

Availability and Support

As of now, ROHM has commenced mass production of both products, and they are readily available for purchase through online distributors such as DigiKey, MOUSER, and Farnell. For developers, evaluation boards are also on offer to support application development and design efforts.

For companies looking to innovate with cutting-edge motor control technologies, ROHM provides a significant step forward. The BD60210FV and BD64950EFJ mark a new chapter in motor driver technology, enabling manufacturers to craft energy-efficient, reliable, and multifaceted devices that align with modern consumer and industrial demands.

Conclusion

ROHM’s commitment to advancing motor driver technology demonstrates its dedication to fostering innovation across multiple sectors. With the ability to function in a wide range of applications while optimizing energy use, these new ICs are set to transform the way we think about the operation of appliances and machinery in our daily lives.
