DRV8434A/DRV8434A-Q1 Stepper Drivers

Texas Instruments DRV8434A/DRV8434A-Q1 Stepper Drivers are fully integrated with two N-channel power MOSFET H-bridge drivers, a micro-stepping indexer, and integrated current sensing. The DRV8434A/DRV8434A-Q1 can drive up to 2.5A full-scale output current (dependent on PCB thermal design). The DRV8434A/DRV8434A-Q1 Stepper Drivers with integrated current sense are designed for industrial and consumer applications. The Texas Instruments DRV8434A-Q1 devices are AEC-Q100 qualified for automotive applications.
