LV8713T-MPB-H

Power management integrated circuits (PMICs) are types of highly specialized semi-conductors designed to monitor, control and deliver stable power supplies to a variety of applications while maintaining high efficiency. PMICs come in all shapes and sizes, with the different series offering different features and capabilities. LV8713T-MPB-H is a type of PMIC designed to drive and control a brushless DC motor. It is often found in robotics, medical equipment, industrial automation and various other automation applications.

The key feature of the LV8713T-MPB-H is its Mechatronics Operating System (MOS)-based platform. This allows for simplified tuning and coordination of motion control components across the entire motion control ecosystem. The MOS system enables users to control up to 6 brushless DC motors simultaneously, without the need for complex digital signal processing algorithms.

The LV8713T-MPB-H integrates motor drivers, current sensing, power monitoring and control functions in a single device. With three motor drive channels and one encoder input channel per axis, the LV8713T-MPB-H can provide very accurate control of brushless DC motors. Its functions are divided into three main components: power conversion, signal management, and current measurement.

The LV8713T-MPB-H is a power conversion component. It provides the necessary power to drive the brushless DC motors from a DC or an AC source. The power conversion is realized by an advanced pulse-width modulation (PWM) control system with flexible current limiting. This ensures that the motors do not become over-current in applications with unpredictable load changes.

The LV8713T-MPB-H also incorporates signal management functions. This includes a three-phase drive circuit that provides adjustable frequency, phase and voltage control of the brushless DC motor. In addition, it has an encoder interface that converts a rotary encoder signal into motor speed and position information, allowing for accurate and smooth motor control. Additionally, it comes with a built-in high-resolution PID controller that automatically adjusts the output voltage to maintain the required motor speed and position.

The current measurement component of the LV8713T-MPB-H is used to monitor and limit the current drawn by the motor. The LV8713T-MPB-H uses a high-resolution analog-to-digital conversion to measure the motor current, thus enabling accurate and efficient current control. It also has an active current limit feature that allows for improved dynamic response and safety.

In addition to the above mentioned features, the LV8713T-MPB-H also supports a variety of communication protocols, such as I2C, PMBus, and CANBus, that facilitate communication between the PMIC and other system components. This makes integrating the LV8713T-MPB-H into existing systems very easy.

Overall, the LV8713T-MPB-H is an effective PMIC designed to drive and control brushless DC motors. Its integration of power conversion, signal management, and current measurement functions makes it a perfect choice for a variety of applications. It is ideal for robotic and medical equipment, industrial automation, and other automating applications.
