Drivers Offer Motor Speed Control Options
ROHM Electronics’ BD62xx Series of H-bridge driver ICs offers designers a simple upgrade path to PWM speed control using either analog or digital inputs. The drivers provide a TTL-compatible interface to an external MCU as well as an internal VREF -PWM conversion circuit for operation from an analog voltage input. The drivers are offered in three voltage classes (7 V, 18 V and 36 V) with current ratings in each class of 0.5 A, 1.0 A and 2.0 A.
