Texas Instruments DRV8816 Dual Half-Bridge Motor Drivers

Texas Instruments DRV8816 Dual Half-Bridge Motor Drivers provide a versatile power driver solution with two independent ½-H bridge drivers. These devices can drive one brushed DC motor or one winding of a stepper motor, as well as other devices like solenoids. A simple INx/ENx interface allows easy interfacing to controller circuits. The output stages use N-channel power MOSFETs configured as ½-H-bridges. The Texas Instruments DRV8816 is capable of peak output currents up to ±2.8A and operating voltages up to 38V. An internal charge pump generates needed gate drive voltages. A low-power sleep mode is provided, which shuts down internal circuitry to achieve a very-low quiescent current draw. This sleep mode can be set using a dedicated nSLEEP pin.
