PMIC - Motor Drivers, Controllers
The BD6964FVM-TR is a three-phase, half-bridge motor driver with integrated pre-drivers, a specialized product from ROHM\'s Motor Control Power Semiconductor Category. This IC enables high-accuracy, high-efficiency rotation control with simple circuitry and a few external components, making it ideal for a variety of applications from consumer appliances to office automation and automotive applications. This article will explain the application fields of this IC and its working principle.The BD6964FVM-TR is a driver IC optimized for continuous current up to 8A in three motors and six directions. It supports PWM or burst mode for speed control, and has two separate drive circuits for independent speed control. This makes it ideal for applications such as air conditioning blower motors, washing machines and pumps. The device is also often used in automotive applications such as electric power steering, door mirror power tilt, and power windows.The BD6964FVM-TR has an integrated full-bridge pre-driver and low-side output circuit, which is capable of driving large external MOSFETs. This enables the driving of three-phase motors as large as 50A with high efficiency. The pre-driver is enabled with a simple current sensing circuit, allowing for faster operation and more accurate speed control than is typically possible.In terms of its operation, the BD6964FVM-TR works by using a PWM signal from a microcontroller to control the output stage. The external MOSFETs are then driven by the internal pre-drivers. When the MOSFETs are driven, a current flows through the motor, enabling it to start and either speed up or slow down. The speed of the motor is then determined by the duty cycle of the PWM signal, allowing for accurate and efficient rotation control.The BD6964FVM-TR also integrates a number of safety and protection circuits, including short-circuit and over-current protection circuits. This ensures maximum safety of the motor, the control system, and any other components connected to it. In addition, the IC also features an inrush current limiter and a thermal shutdown circuit to protect both the motor and its control system in the event of an over-temperature condition. Finally, the IC is designed such that the output voltage can be monitored to ensure that the motor is operated within its specified range.Overall, the BD6964FVM-TR is an ideal driver IC for a wide range of motor applications, from consumer appliances to automotive applications. The integrated pre-drivers and protection circuits enable high-accuracy and high-efficiency rotation control, as well as maximum safety for the motor, the control system, and any other connected components.The specific data is subject to PDF, and the above content is for reference
