Motor Driver ICs

Texas Instruments DRV8840 / DRV8842 / DRV8843 motor driver ICs are integrated motor drive solutions for printers, scanners, and other automated equipment applications. TI DRV8840 DC motor driver ICs have one H-bridge driver and are intended to drive one DC motor. DRV8842 DC motor driver ICs have one H-bridge driver and are intended to drive one DC motor, one coil of a stepper motor, or other loads. TI DRV8843 dual H-bridge driver ICs have two H-bridge drivers and can be used to drive two DC motors, one stepper motor, or other loads. The DRV8840 can supply up to 5A peak or 3.5A output current. The DRV8842 can supply up to 5A peak or 3.5A RMS output current. The DRV8843 can supply up to 2.5A peak or 1.75A RMS output current.
