DRV8837 Motor Driver

Texas Instruments' DRV8837 provides an integrated motor-driver solution for cameras, consumer products, toys, and other low-voltage or battery-powered motion-control applications. The device has one H-bridge driver, and can drive one DC motor or one winding of a stepper motor, as well as other devices such as solenoids. The output driver block consists of N-channel power MOSFETs configured as an H-bridge to drive the motor winding. An internal charge pump generates needed gate-drive voltages.

The DRV8837 can supply up to 1.8 A of output current. It operates on a motor power-supply voltage from 1.8 V to 11 V, and a device power-supply voltage of 1.8 V to 7 V.
