Rohm Co., Ltd. has rolled out two progressive motor driver ICs engineered for brushed DC motors, the BD60210FV (20V, 2ch) and BD64950EFJ (40V, 1ch). These chips are designed with a watch in direction of wide-ranging functions in house and workplace home equipment, together with fridges, air conditioners, printers, and robotic vacuum cleaners.
The transfer is available in response to the burgeoning electrification of client and industrial gear, notably within the area of white items, which has sparked a rising demand for energy-efficient brushed DC motors. However, the motor drivers within the present market are anticipated to cater to various functions and use instances whereas concurrently lowering exterior part rely and dimension.
The BD60210FV and BD64950EFJ not solely assist a wide selection of platform designs however are additionally apt for product redesigns and spinoff merchandise. They guarantee ultra-low standby present (Typ: 0.0 microampere, Max: 1.0 microampere), thereby contributing considerably to energy financial savings throughout standby operation.
The BD60210FV might be utilized as a twin H-bridge (2ch) motor driver with direct PWM management, able to driving two DC brush motors, a bipolar stepper motor driver, or solenoid driver. Its H-Bridge circuit configuration obviates the requirement for a lift circuit, thereby minimizing exterior elements, and aids in space-saving and simplified design.
The BD64950EFJ comes with a single H-bridge (1ch) that allows each direct PWM management and fixed present PWM management. Its low on-resistance design mitigates warmth era, facilitating environment friendly motor drive.
Both merchandise can be found for buy on-line from distributors comparable to DigiKey, MOUSER and Farnell. Evaluation boards supporting utility improvement and design are additionally obtainable.
These new ICs will discover their functions in quite a lot of contexts – together with however not restricted to rotation management in ice makers for fridges, louver management in air conditioners, carriage motion in printers and brush rotation in robotic vacuum cleaners, along with operation management in automated doorways or shutters and transport management in small conveyors.
