Texas Instruments DRV8834/35/36 Dual Low Voltage H-Bridge ICs

Texas Instruments DRV8834 / DRV8835 / DRV8836 Dual Low Voltage H-Bridge ICs have two H-bridge drivers and can drive one stepper motor, two DC motors, and other devices like solenoids. The output driver block of each H-bridge consists of N-channel power MOSFETs configured as an H-bridge to drive the motor windings. Each H-bridge includes circuitry to regulate or limit the winding current. TI DRV8834 / DRV8835 / DRV8836 H-bridge drivers can drive up to 1.5A continuous output current. These TI devices provide an integrated motor driver solution for toys, printers, cameras, and other low-voltage or battery-powered motion control applications.
