ROHM Semiconductor has introduced two new motor driver ICs for brushed DC motor applications: the BD60210FV, a 20 V dual-channel device, and the BD64950EFJ, a 40 V single-channel solution.
Rising demand for energy-efficient brushed DC motors in both consumer and industrial products—especially white goods—has increased the need for compact, efficient motor driver ICs that reduce external components and overall system size. Addressing these needs, ROHM’s latest ICs feature flexible package designs that support both new product platforms and upgrades to existing system architectures.
Both devices deliver extremely low standby current, with a typical value of 0.0 μA and a maximum of 1.0 μA, helping improve overall power efficiency.
The BD60210FV is a dual H-bridge, two-channel motor driver that supports direct PWM control. It can drive two brushed DC motors, a bipolar stepper motor, or solenoids, operating across an input voltage range of 8 V to 18 V. The device provides 1 A continuous current per phase and up to 4 A peak current per phase.
The BD64950EFJ integrates a single H-bridge channel and supports both direct PWM and constant-current PWM control. With a 40 V withstand voltage, it delivers 3.5 A continuous current and up to 6 A peak current, making it ideal for high-power brushed DC motors used in 24 V systems.
Both motor driver ICs are now in mass production. To aid design and evaluation, ROHM has also released dedicated evaluation boards—BD60210FV-EVK-001 and BD64950EFJ-EVK-001.
Target applications include a wide range of consumer products such as refrigerators, air conditioners, printers, robotic vacuum cleaners, water heaters, rice cookers, and humidifiers. In industrial settings, the ICs are suitable for automatic doors, shutters, small conveyors, power tools, and other compact motor control systems.
