BD6210F-E2 Application Field and Working Principle

The BD6210F-E2 is a PMIC (Power Management Integrated Circuit) device with motor drive, controller, and regualtor consumption. It combines several functions, such as motor speed and direction control, motor drive, sensorless control, and overload protection, into one chip. The BD6210F-E2 has a wide range of applications in various home appliances, including robotic vacuums, toasters, washing machines, and electric bicycles. This article will discuss the application field and working principle of the BD6210F-E2.

Application Field

The BD6210F-E2 is a low cost and highly integrated chip designed for electric motor applications. It supports 3-phase brushless DC and AC motors, as well as 2-phase hybrid stepper motors. Its high integration and low cost make it suitable for smart homes, small electric tools, and consumer electronics. Furthermore, it can also be used for automotive applications such as electric fans, actuators, etc.

The BD6210F-E2 includes various features such as Motor Sensorless Control, Motor Drive, Voltage Monitor, Overload Protection, and Stall Protection integrated into one 8-pin WLLFN package. The on-chip voltage monitor has two voltage outputs, which can be used to monitor the motor current and detect the motor temperature. The Overload Protection and Stall Protection features are enabled through the Overcurrent Flag (OCF) and Stall Flag (SF) pins, respectively. These features make the device robust against current and temperature overloads.

Working Principle

The BD6210F-E2 is a three-phase brushless DC and stepper motor driver IC that works with a fixed power supply or a DC-DC switching power supply. The device has an on-chip H-bridge driver and 3-phase PWM generator, allowing for precise speed and direction control.

The PWM generator generates a Trapezoidal current waveform, which is used to provide precise and smooth motor control. This waveform minimizes the amount of current drawn from the power supply and eliminates torque ripple, resulting in smoother operation and higher efficiency.

The motor speed and direction are controlled by a control signal sent to the device. The control signal can be either an Analog Voltage signal, or a PWM signal. The BD6210F-E2 supports both Sensorless and Sensored Control, allowing for both closed loop and open loop speed and direction control. This allows for precise control of the motor speed and direction, as well as for acceleration and deceleration control. The device also has safety features such as Overload Protection and Stall Protection, which protect the device from current or temperature overloads.

Conclusion

The BD6210F-E2 is a highly integrated PMIC device with motor drive, controller, and regulator functions. It is suitable for various home appliances, electric tools, and consumer electronics. It has features such as motor sensorless control, motor direction and speed control, voltage monitor, overload protection, and stall protection. It also supports both analog and PWM control signals, allowing for precise speed and direction control. This makes it a great choice for motor control applications.
