The BH6565FV-E2 is a two-phase brushless DC motor driver with all necessary control functions integrated into a single package. This type of motor driver is a component widely used in power management integrated circuit (PMIC) applications, specifically for motor drivers, controllers and other systems requiring motion control. The driver is designed to offer superior speed range, efficiency and power saving features. This motor driver is designed to offer optimal performance for applications requiring performance, precision and reliability, such as Unmanned Aerial Vehicle (UAV) and Robot Manipulation systems, robotics, industrial control and automation.

The BH6565FV-E2 motor driver incorporates a “Sine Wave” drive architecture to precisely control the motion of the motor. This type of drive architecture allows for smoother operation, increased accuracy, improved efficiency, quieter operation and easier component integration with other systems. In addition, this type of drive architecture is more cost effective and power efficient than other typical PMIC motor driver designs.

Other features of the BH6565FV-E2 include: Electronic Speed Control (ESC), Hall Effect Sensor support, Current Feedback and over current protection, fail-safe operation, configurable output parameters and inverter operation. For example, the ESC allows the user to adjust the speed and control the direction of the motor, while the current feedback and over current protection features protect the motor from overcurrent conditions. In addition, the BH6565FV-E2 has a built-in thermal protection circuit that prevents the driver from over-temping during operation.

The sine wave drive architecture of the BH6565FV-E2 utilizes three power transistors for upper, lower and side phases of the motor. In this architecture, the primary MOSFETs are used to control the currents through the phases of the motor. The main advantage of this drive system is that it provides a very linear motor current output over the full speed range. The power transistors are driven with complementary PWM signals, while the corresponding fault flags are monitored. The MOSFETs are also protected against over current with two independent current limit circuits.

The BH6565FV-E2 also features a built-in amplifier for driving up to 2A continuous current output. This feature eliminates the need for a separate amplifier, reducing the overall power supply requirements of the system. The motor driver also provides several protections and power saving features, including overheating protection, over current or short circuit protection, and short circuit brake function.

In summary, the BH6565FV-E2 motor driver is an ideal PMIC device for applications requiring performance, precision and reliability. Its sine wave drive architecture provides smooth and accurate control of the motor current, while its integrated ESC, Hall Effect Sensor, current feedback, over current protection and thermal protection circuits offer superior power savings, protection and reliability.
