Working Principle

Modern electronic control systems use PMICs as an economical and efficient motor driving technology that allows for precise speed, torque, and position control. ATA6826C-TUQY-66 combines a PWM regulator and three-phase motor driver into one integrated circuit, providing an integrated power stage solution with advanced features and enhanced performance.

The ATA6826C-TUQY-66 operates by generating a sinusoidal waveform for each phase of the motor. The sinusoidal waveform is generated by a three-phase voltage source, and is then fed into the inverter boards for PWM control. The PWM control acts as a switch, opening and closing the switches accordingly to vary the magnitude and frequency of the output voltage waveforms. By regulating the pulse-widths and frequency, the ATA6826C-TUQY-66 precisely controls the amount of charge on the motor\'s windings, allowing for precise speed, torque, and position control over the motor.

The ATA6826C-TUQY-66 also includes current sensing capabilities to actively monitor the amount of current flowing through the motor\'s windings and detect faults. The current sensing capabilities also enable the ATA6826C-TUQY-66 to detect short-circuited or open-circuited windings, making it a reliable motor control solution. The chip also includes an internal body diode to reduce switching losses, and integrated over-temperature protection for improved reliability.

Conclusion

The ATA6826C-TUQY-66 is an integrated motor control solution designed for motor-driven applications, providing precise speed and torque control, advanced features, and improved reliability. Its combination of a PWM regulator and three-phase motor driver make it an ideal solution for a wide range of motor-driven applications, where precise speed, torque, and position control is required.
