What is a Brushless DC Motor Drivers?
Brushless DC Motor Driver is used to drive the voltage and current of brushless DC motor stator windings in a sequence. The sequence of stator windings energizations is determined by the relative positions of stator and rotor. The relative positions of stator and rotor are measured by using Hall-effect sensors/encoders or by measuring back electromagnetic force (EMF) due to rotation of the rotor.
Brushless DC Motor Driver consists of a gate driver and power driver circuits to drive the motor windings, control logic circuits, PWM generating circuits, serial interface circuits, and has protection features such as under-voltage Lockout (UVLO) protection, over-voltage protection, short circuit protection, over current protection, and thermal protection.
Key features of the Brushless DC Motor Drivers:
- Support analog and PWM speed control.
- Support sinusoidal/field-oriented control (FOC)/trapezoidal control technique.
- Built-in motor rotational speed monitor circuit.
- Supply Undervoltage lock-out protection.
- Thermal warning and thermal shutdown (TSD).
- Supports analog or digital Hall inputs.
- Over-current detection.
- Support register mode (motor operation and parameters setting by writing to the register via serial interface).
- Short circuit protection.
- Support direct and SPI/I2C interface.
- Motor- lock detect and restart.
Brushless DC Motor Drivers are ideal for use in the aerospace industry satellites, gyroscope, artificial, heart pumps, disc drives, video recorders, and biomedical fields, brushless-DC (BLDC) motor modules, small home appliances, office automation machines, factory automation, and robotics, automotive LIDAR, medical science, lap equipment, camera lens adjustment, printing, winding machines, textile machines, bonding machines, wafer processing, antenna adjustments, printers, surveillance cameras, power tools, cash and ticket machines, and instrumentation.
