Application Field

DRV8701PRGET is mainly applied in industrial, automotive, and power-tool applications. It addresses the issues typically encountered in motor control applications: providing a reliable and efficient environment for operation; maximizing system efficiency; minimizing cost; and controlling noise and output noise. Additionally, by optimizing the system architecture, DRV8701PRGET provides the opportunity to design smaller, lighter and more efficient systems. The integration of DRV8701PRGET technology enables the development of cost effective, reliable and efficient performance.

This technology is suitable for a wide range of motor control applications. It can be applied to drive permanent magnet (PM) motors, brushless DC motors, stepper motors, micro-mechanical motors, and more. It is also suitable for controlling speed and torque of motor-driven applications. This can be done by monitoring current, torque, and frequency during operations.

Working Principle

DRV8701PRGET integrates the advanced motor control algorithms of Texas Instruments, together with Gates Logic, the ultra-fast microprocessor, and efficient power switching technology to offer the perfect motor control solution for operating. In order to further optimize the system, DRV8701PRGET integrates several features that can be used simultaneously to control motors with speed and torque, such as current and torque monitor mode, step driving control mode, PWM control mode, and simple voltage control.

In the current and torque monitor mode, DRV8701PRGET monitors the current and torque of the motor during operation in order to react quickly and efficiently in case of any abnormalities. In the step driving control mode, the electronics measure and adjust the direction, speed, and torque according to the commands input. This enables a perfectly accurate and precise control of the motor.

In PWM control mode, DRV8701PRGET modulates the speed and torque of the motor according to the commands input by using the pulse width modulation (PWM). This mode is suitable for high speed applications, as it offers more precise control over the operation. Lastly, in the simple voltage control mode, DRV8701PRGET pulses the voltage output at the frequency of the commanded input, offering a more efficient but less precise control over the motor.
