The SLA7071MPR is a monolithic IC manufactured with the Reliability Enhanced BiCMOS (REB) process. The part provides all the necessary circuitry to implement bidirectional motion control of brushless and geared DC motors, making it suitable for a broad range of applications. This paper focuses on the application field and working principle of the SLA7071MPR.
Application Field
The SLA7071MPR can be used in a wide range of applications, from small consumers and industrial to automotive. These applications can be divided into three main categories: Position Control, Speed Control, and Torque Control.
Position Control
The SLA7071MPR can be used for precise positional control of DC motors. This type of control requires the slower speed and higher accuracy of closed-loop systems. In position control, the motor speed and torque is regulated to achieve accurate and repeatable position results. This is often used in robotic and machine automation applications.
Speed Control
The SLA7071MPR can also be used for speed control of DC motors. These motors are generally used for controlling velocity-dependent tasks, such as in conveyor belts, conveyor systems and robotic systems. The motor speed can be controlled via pulse-width modulation (PWM) for precise and repeatable speeds.
Torque Control
The SLA7071MPR can be used for precise torque control of DC motors. This type of control is usually used to control the load torque, such as in elevator control systems, machine automation and servo systems. The motor torque is regulated via PWM control to match the load torque accurately and reliably.
Working Principle
The SLA7071MPR integrates all the components and circuitry needed to perform bidirectional motion control of DC motors -including a power FET driver and its associated gate drivers, an overcurrent protection block, a temperature monitoring circuit and signal input amplifiers. The part is capable of both current control and torque control, making it suitable for a broad range of applications.
Power Stage
The SLA7071MPR has a high-performance power stage comprised of two high-current power FETs and their associated gate drivers. The power FETs are driven via pulse-width modulation (PWM) to regulate the current through the motor, allowing for precise and repeatable motor control. The power stage has protection against overcurrent, undervoltage lockout and over-temperature.
Current Control
The SLA7071MPR features a current sensing circuit that reads the motor current via an external sense resistor. This allows for precise current control of the motor, with the current being regulated via pulse-width modulation (PWM) of the power FETs. This provides adjustable current control for speed and torque applications.
Torque Control
The SLA7071MPR incorporates a torque control circuit, which is able to regulate the motor torque via an external torque control resistor. The motor current is regulated via pulse-width modulation (PWM) of the power FETs. This allows for precise and repeatable torque control in both open- and closed-loop systems.
Signal Processing
The SLA7071MPR includes an analog signal processing block for signal conditioning and amplification. This includes an operation amplifier and comparator, which are used to amplify and filter velocity, position and torque signals, as well as to generate error signals for closed-loop control.
Protection
The SLA7071MPR features a comprehensive protection circuity, which includes overcurrent protection, over-temperature protection and undervoltage lockout. This ensures the part is protected against any external faults, such as overloads and power supply failures.
Conclusion
The SLA7071MPR is a monolithic IC suitable for a broad range of motion control applications. It features a high-performance power stage, current control and torque control capabilities, as well as comprehensive protection circuitry for reliable operation. The part is suitable for both open- and closed-loop control, making it a suitable choice for automotive, industrial and consumer applications.
