STMicroelectronics AEK-MOT-2DC70S1 Automotive Dual DC Motor Driver

STMicroelectronics AEK-MOT-2DC70S1 Automotive Dual DC Motor Driver is a reference design for a multi DC motor driving application, providing up to 15A per device. This compact motor driver solution embeds all of the driver and signal decoding functions on a single board. Together with the current sensing capability, the AEK-MOT-2DC70S1 features three independent encoder inputs. The DC motor drivers have separate half-bridge driving, which allows up to three separate motors with only two devices, using an appropriate driving sequence.

The AEK-MOT-2DC70S1 Motor Driver design is ideal for two-wheel applications and allows engineers to build highly compact motor control solutions. The two high-side drivers facilitate additional driving for system actuators, such as unidirectional DC motors, LEDs, and pumps.
