In recent years, the electrification of industrial and consumer equipment, especially household appliances, has accelerated, increasing the demand for energy-efficient brushed DC motors. At the same time, motor controllers are expected to support multiple applications and use cases while reducing the number and size of external components.
To meet these needs, these new products utilize highly versatile packaging, making them ideal not only for new platform designs but also for redesigns and derivative products. Furthermore, they achieve an ultra-low standby current (typ: 0.0 µA, max: 1.0 µA), which significantly contributes to energy savings during standby operation.
The BD60210FV can function as a dual H-bridge (2-channel) motor driver with direct PWM (pulse-width modulation) control, capable of driving two brushed DC motors, a bipolar step-down motor driver, or a solenoid driver. Its H-bridge circuit configuration eliminates the need for a boost circuit, minimizing external components and contributing to space savings and a simpler design. It supports an input voltage of 8V to 18V, a continuous current of 1A/phase, and a peak current of 4A/phase.
The BD64950EFJ features a single-channel H-bridge that supports both direct PWM and constant-current PWM control. Its low-resistance design reduces heat generation, enabling efficient motor drive. With a non-disruptive voltage of 40 V and a continuous current of 3.5 A (6 A peak), it is suitable for high-power, high-voltage (24 V) brushed DC motor applications.
Both products are now in mass production. Online sales have also begun, and these products (BD60210FV and BD64950EFJ) can be purchased from online retailers such as DigiKey, MOUSER, and Farnell. Evaluation boards (BD60210FV-EVK-001 and BD64950EFJ-EVK-001) are also available to support application development and design.
ROHM will continue to expand its motor drive solutions for industrial and consumer equipment, contributing to greater comfort and energy savings in society.
