The DRV8830DRCT is a low voltage brushed DC Motor Driver with speed regulation (I2C ctrl). 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 MOSFETs configured as an H-bridge to drive the motor winding. Provided with sufficient PCB heat sinking, the DRV8830 can supply up to 1A of DC/RMS or peak output current. It operates on power supply voltages from 2.75 to 6.8V. To maintain constant motor speed over varying battery voltages while maintaining long battery life, a PWM voltage regulation method is provided. The output voltage is programmed through an I2C-compatible interface, using an internal voltage reference and DAC. Internal protection functions are provided for overcurrent protection, short-circuit protection, under-voltage lockout and over-temperature protection.
