PMIC - Motor Drivers, Controllers refer to the electronic components used to control the motion of motors and other electrical appliances. Among the most common motor driver components, LV8734VL-MPB-H stands out as a viable and reliable option for the control of numerous motor models. The aim of the following article is to provide an overview of its application field and working principle.

Applications

LV8734VL-MPB-H has a wide application field. It is a motor driver controlling component suited for brushed, brushless, and stepper motors. It has special features, such as over-voltage, over-current and overheating protection, which make it ideal for use with high-current motors, as well as low-power applications. It also supports a wide range of operating voltages, making it an ideal choice for a wide range of voltage levels. As an additional advantage, it is capable of controlling two motors separately.

Working Principle

The working principle of LV8734VL-MPB-H, is quite simple. When the motor driver is powered on, the voltage level on its output is determined by the supply voltage level, as well as the on-board settings. The output voltage level can then be either maintained or adjusted, depending on the particular application. It uses an open-loop control system, meaning that current signals are transmitted differently to the motors, whereas in a closed-loop system, the current signals are generated by the motor and returned to the controller for accuracy and improved control. This yields higher performance and reliability.

To adjust the speed, the motor driver relies on the ability of its power MOSFETs to invert the polarity of the output voltage, and therefore, the direction in which the motor turns. By controlling the current passing through the MOSFETs, the motor can be changed from one speed setting to another, allowing for precise speed adjustments. Additionally, the power MOSFETs also help protect the motor from over-current, over-voltage, and over-temperature.

As for the user’s interface, LV8734VL-MPB-H features a PWM (pulse width modulation) input, enabling users to control the motor’s speed and direction. Additionally, it features an SPI (Serial Peripheral Interface) compatible with any type of motor control processor, such as the ATmega32 32-bit microcontroller, the 8051 family, and alternative microcontroller solutions.

Conclusion

Overall, LV8734VL-MPB-H is a powerful and reliable motor driver, suitable for a wide range of applications. Its open loop control system yields higher performance and reliability compared to closed loop systems, while its protective hardware helps to protect the motors from temperature, over-voltage, and over-current overstress. To cap it off, its user-friendly interface, compatible with a wide array of microcontrollers, allows for quick and efficient setup and control of motors.
