Texas Instruments' DRV8830 provides an integrated motor driver solution for battery-powered toys, printers, 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 loads like solenoids.
The output driver block consists of N-channel and P-channel power MOSFET’s configured as an H-bridge to drive the motor winding. Provided with sufficient PCB heatsinking, the DRV8830 can supply up to 1 A of continuous output current. It operates on power supply voltages from 2.75 V to 6 V.
