Texas Instruments DRV8840 DC Motor Drivers

Texas Instruments DRV8840 DC Motor Drivers are 5A brushed DC drivers with inrush protection, ideal for automated equipment applications. These drivers include one H-bridge driver and are intended to drive one DC motor. The DRV8840 drivers can supply up to 5A peak or 3.5A output current. These drivers come with a decay mode that is programmable to allow braking or coasting of the motor when disabled. Features include overcurrent protection, short-circuit protection, under-voltage lockout, and over-temperature. The Texas Instruments DRV8840 DC motor drivers are available in a 28-pin HTSSOP package with PowerPAD™. Applications include printers, scanners, gaming machines, office automation machines, factory automation, and robotics. Compared to the DRV8840, the DRV8874 saves BOM space and cost by eliminating sense resistors.
