The BD6971FV-E2 voltage regulator is an IC motor driver and controller module that provides efficient motor control and driver solutions, while maintaining high reliability and quality. This IC module can provide up to 3.2A current, and have built-in temperature and overcurrent protection features to protect against excessive voltage and current. It also includes a built-in SPWM (Space Vector Pulse Width Modulation) generator and pulse-by-pulse current limitation technology.

The main application field for the BD6971FV-E2 is for brushless DC (BLDC) motors, stepper motors,AC induction motors, and multi-motor control applications. It is designed for automotive, industrialControl, home appliance, and elevator applications. The combination of the current compensation,variable frequency and SPWM technology makes the BD6971FV-E2 effective for different applications and technology with high precision,high response and reliability.

The BD6971FV-E2 works by sensing the back EMF of the motor and processing the sensed signal by its internal MCU. Then, the MCU generates and supplies three-phase PWM signals to drive the motor. The PWM signals are generated by the built-in SPWM generator which oscillates at a high frequency and generates alternating sine waves from the input voltage. These signals are then regulated to provide an accurate and efficient current to the motor. The SPWM feedback loop also helps to control the motor speed accurately and consistently.

The BD6971FV-E2 also features current control technology, which helps in regulating the output current to the motor and providing safe operation in case of overload or short circuit. The built-in current control monitoring always checks the current values and adjusts the voltage level accordingly. This ensures that the motor always operates within its safe operating range and that excessive current levels are not reached. Low-side drive capability of the BD6971FV-E2 also allows for reversible and bidirectional control of the motor.

The BD6971FV-E2 module provides an efficient control solution for brushless DC motors and stepper motors by combining the above features. Its user-friendly configuration and features make it a valuable choice for controlling and driving high-power brushless DC motors. Its high resolution and low noise technology makes it ideal for applications that require high precision and reliability. The module is designed to offer optimum efficiency and high performance, while providing a superior current control solution with great accuracy.
