低压马达驱动器IC LOW-VOLTAGE MOTOR DRIVER IC

The is a low voltage brushed DC Motor Driver with VOLTAGE REGULAON IN1/IN2 Ctrl. It is suitable 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 MOSFETs configured as an H-bridge to drive the motor winding. Provided with sufficient PCB heat sinking, it can supply up to 1A of DC/RMS or peak output current. The device 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. An input pin allows programming of the regulated voltage. A built-in voltage reference output is also provided.
