Motor Control SoC Improves Efficiency, Cuts Noise and Component Count
Single chip, three phase, sine wave drivers
Toshiba Electronics Europe has expanded its family of System on Chip (SoC) motor drive solutions with a three phase, sine wave PWM driver. They reduce component count and noise and improve the efficiency of BrushLess DC (BLDC) motor applications.
The TB6585FG Application Specific Standard Product (ASSP) is a complete motor driver solution that integrates commutation logic, sine wave PWM generation, Hall sensor amplification, motor drive power stage and protection functionality into a single,
An analogue signal input enables the TB6585FG to modify the PWM duty cycle and control forward or reverse motor rotation speed. Combining a triangular waveform generated
By providing sinusoidal waveforms to drive the motor phases, the TB6585FG helps minimise electrical and acoustic noise when polarities in the driver circuit switch between positive and negative. This promotes more efficient operation, helps to reduce vibrations and enhances reliability. The ability to control lead angle allows a designer to tune the delay between current and voltage phases, which further improves efficiency in the target application.
The TB6585FG offers configurable modes for improving motor start- up characteristics and has inbuilt protection against overcurrent conditions. An ability to detect excessive commutation frequency and low rotation speed also improves design flexibility.
