The SLA7080MPR is a motor driver and controller in the PMIC – Motor Drivers, Controllers category. It is a high-performance single-axis motor driver capable of controlling two-phase, three-phase, and four-phase DC-brush, brushless DC (BLDC), and stepper motors. In addition to its motor-driving capabilities, the SLA7080MPR contains a microprocessor-compatible command interface, an embedded-motion controller, a set of GPIO pins, and other features necessary for sophisticated motion-control applications.

The SLA7080MPR can be used to drive one or two brushed DC motors or stepper motors, and includes a single-axis microstepping controller for controlling BLDC motors.The SLA7080MPR uses pulse-width-modulation (PWM) and current-mode control. One or two pulses are applied to the gate drive pin, along with the current sense signals, to the SLA7080MPR, depending on the motor-type being controlled. The SLA7080MPR, then, modulates the voltage and current to produce a motor output according to an algorithm contained in the firmware. This motor output, along with GPIO pins and the command interface, can be further manipulated to drive sophisticated motor-control applications.

The SLA7080MPR has an array of features that allow engineers to integrate the best motor-control techniques into their applications. These features include: a 16-bit timer, a 64-slot speed profile RAM, an optional reverse signal detection, over temperature protection, and an 8-bit a/d converter for voltage and current sensing. In addition, the SLA7080MPR provides specialized motion-control functions such as software-selectable microstepping back-emf compensation, as well as output phase and frequency measurements. The on-chip oscillator of the SLA7080MPR can be used to generate the frequencies necessary to meet motion-control standards. The SLA7080MPR also provides an isolated SPI interface for control and programming that allows design engineers to quickly and easily integrate the device into their existing environments.

The SLA7080MPR can also be integrated with other motor-control solutions such as motor feedback systems and motor encoders. This integration allows engineers to build more sophisticated and accurate motor-control systems. For example, a motor feedback system can be used to constantly measure the motor-speed, position and current, while an encoder can measure the motor speed and position in addition to providing stall detection.

The SLA7080MPR is an ideal motor-driver and controller for motor-oriented industrial, commercial and consumer applications. Its array of features make it a versatile solution for many different types of motor-control applications. From brushless DC motors used in robotics and medical equipment to stepper motors used in instrumentation and automation, the SLA7080MPR is a reliable and robust solution for motion-control applications.
