PMIC - Motor Drivers, Controllers are essential components for a wide variety of electric systems. The BD6701F-E2 application field and working principle is one of these popular devices, known for its efficiency, accuracy, and flexibility. It is a full bridge driver with different protection functions and integrated with a high level of speed control capabilities. The BD6701F-E2 is typically used in brushless DC motor systems and automotive applications including electric power steering (EPS), windshield wipers, and window washers.

The main purpose of the BD6701F-E2 is to accurately and efficiently drive a brushless DC motor. It utilizes a full-bridge structure with both high and low MOSFETs which provide four different operating modes. The operating modes, including forward, reverse, coast, and brake, all provide the control needed to achieve the desired speed of the BLDC motor.

The BD6701F-E2 also has two protection functions. The standing wave protection function helps reduce standing waves on the power line in order to prevent them from causing damage to the device. The over current protection function helps protect the device from overloads, as well as providing a warning signal before an overload occurs.

The control for the BD6701F-E2 is provided by an external signal from the controller. The controller will monitor the rotation of the BLDC motor and then send the appropriate signal to the BD6701F-E2. This signal is then used to set the required operating mode. The signal also provides a direction signal which will indicate which direction the motor should rotate in. The signal will also provide a duty cycle signal which is used to set the speed of the motor.

The BD6701F-E2 has a maximum of three channels which are used to control the motor speed. These channels are referred to as the V0, V1 and V2 signals. The V0 signal is used to control the static speed of the motor while the V1 and V2 signals are used to control the dynamic speed of the motor. The V1 and V2 signals are typically generated from a PWM signal from a controller.

In addition to the three-channel control, the BD6701F-E2 also includes an additional control signal known as the C signal. This signal is used to control the level of phase modulation and can be used to increase or decrease the speed of the motor. By varying the C signal, the level of phase modulation can be adjusted to achieve the desired level of control for the motor.

The BD6701F-E2 also includes a current sense function which can be used to monitor the motor current. This function is used to detect any overload conditions and will provide a warning signal to help prevent any overloading issues.

The BD6701F-E2 provides an excellent solution for a variety of BLDC motor control applications. It has a full bridge structure with different operating modes and protections, and provides accurate and efficient motor control. With it\'s integrated current sense and PWM control signals, the BD6701F-E2 is the perfect choice for any BLDC motor control application.
