DRV8881ERHRT Application Fields

DRV8881ERHRT can be used in a variety of automotive, consumer and industrial applications, such as DVD players, CD players, robotic arms and legs, office automation equipment, small household appliances, etc. In addition, the DRV8881ERHRT is compatible with a wide range of commonly used microcontrollers and development boards, such as Arduino and Raspberry Pi.

The DRV8881ERHRT is especially suitable for applications such as transmission, fan drives, and pumping, where small steps and high accuracy and torque are required. Its adjustable current control, wide range, and low voltage capability make it an ideal choice for these applications.

DRV8881ERHRT Working Principle

The DRV8881ERHRT integrates two full H-bridge drivers to drive two-phase bipolar stepper motors. It is able to support up to 2A peak current per phase, and can run as high as 30V. The DRV8881ERHRT also integrates protection functions, such as thermal protection, overvoltage protection, and undervoltage protection.

The main working principle of the DRV8881ERHRT is to drive a stepper motor by applying a current from the motor’s own winding. Thus, the motor is controlled by the applied current. The current is controlled by the pulse-width modulation (PWM), and the direction of the motor is controlled by the direction of the applied current. The DRV8881ERHRT can be configured to operate in slow-decay mode for silent running, or fast-decay mode for quick response. The user can easily adjust the output current as required.

The DRV8881ERHRT is a convenient and efficient stepper motor driver solution, combining a wide range of features and functions into a single component. With its robust operating temperature range, high power, high speed, and low noise operation, it is an excellent choice for automotive, consumer and industrial applications.
