The BD62012AFS-E2 is a brushless DC motor driver based on a maximum efficiency solution, suitable for driving a medium or full load BLDC fan with speed between 2800/min and 16000/min. The device offers integrated full bridge, PWM control and has a half bridge drive built-in. The maximum load current is up to 0.5A and the maximum driver voltage is 15V, making the BD62012AFS-E2 ideal for the segment of small fans.

Application Field

The BD62012AFS-E2 motor driver is suitable for driving blower, centrifugal and axial fans in applications such as air conditioners, air purifiers, exhaust fans and power supplies. Due to its high efficiency, the device also offers great performance in other applications with high speed, like LED lamp and pumps. Furthermore, its interface is compatible with different micro-controllers, making integration with existing systems much easier.

Working Principle

The BD62012AFS-E2 is based on an analogue half-bridge drive with PWM logic, making it able to drive a wide range of motor speeds, from 2800/min to 16000/min.The device features internal soft-start, over-current and over-voltage protections and a low current stand-by mode. In addition, it is capable of restoring the motor from stand-by to running state with feedback from the motor.

The BD62012AFS-E2 motor driver has a Built-in Temperature Compensated System (TCS), which helps to reduce motor hunting and increase motor reliability. The TCS adjusts the motor start up speed by itself and provides protection against over-speed exceptions, making the system safer and more reliable.

The BD62012AFS-E2 also has a CAN interface which provides accurate real-time response and remote control, making it suitable for use in applications with remote performance monitoring and control.

Conclusion

The BD62012AFS-E2 motor driver is a cost effective solution for driving small and medium size brushless DC motors. It presents multiple protections and a built-in Temperature Compensated System to provide a reliable, safe and accurate motor control solution. Its CAN interface allows real-time response and remote control, making it a great device for applications with heavy speed requirements, such as small and medium size fan motors.
