Main Features

BD6387EFV-E2 provides superior performance and flexibility in single-chip motor control applications. It offers the following features:• High-speed motor control: BD6387EFV-E2 is designed to provide fast and precise control of up to four-phase brushless DC motors. The brushless DC motor is driven by PWM-based sensorless control.• Low-voltage and low-power operation: BD6387EFV-E2 operates on supply voltages as low as 1.8V to 7V, resulting in minimal power dissipation.• Advance speed control: This device includes a speed control loop and a dual-current loop control system to keep motor speed fixed with as little noise and vibration as possible. • Position control: The position control loop provides precision control of the motor position, allowing for complex motion control.• Protection features: BD6387EFV-E2 features sophisticated protection circuitry that prevents damage to the motor resulting from over-current and over-temperature conditions.• Interfaces: BD6387EFV-E2 has two slow-speed control interface options (inter-IC or SPI) and two fast-speed control interface options (PWM or Sensorless).

Working Principle

BD6387EFV-E2 uses a 32-bit RISC microprocessor to control motor operations. The on-chip processor processes position, speed and torque data to allow precise control of motor speed, torque and position.The chip contains a six-channel ADC (Analog to Digital Converter) that detects the motor speed and torque in real time, and adjusts the voltage accordingly. The chip also includes an integrated PWM generator that sends out motor control signals. It also has multiple protection circuits that protect the motor from damage due to over-current, over-temperature, and other abnormal conditions.To control motor operations, the chip uses three types of control systems: speed control, position control and dual current control. The speed control system uses the data from the ADC to calculate the desired motor speed, and then adjusts the voltage to keep the motor at the correct speed. The position control system uses the data from the ADC to adjust the motor\'s position. The dual current control system allows the chip to accurately maintain the correct current levels in the motor.In addition, the chip contains a built-in diagnostic feature that allows users to monitor the motor\'s performance and detect any malfunctions or errors.Overall, BD6387EFV-E2 provides efficient and precise control of brushless DC motors, making it the ideal choice for motor control applications that require high accuracy and low power consumption.
