MB86967PFV-G-BNDE1 is a low-cost IC chip developed for automotive applications. It comes in three packages: SO-8, SOT-223, and SOT-23. This chip is the most advanced and robust for driving brushless motors and brushed DC motors. It works as a digital closed-loop controller of motor motion.

This chip is mostly used in the fields of automotive, industrial, and consumer applications. It can control not only automotive but also industrial terrestrial motors, robotic solutions, motor drives for medical and service robots, as well as other motor control applications.

The working principle of the targeted IC chip is composed of the following three parts: a power supply control, a periodic control, and a speed control.

Accounting for the power supply control, it requires an external DC voltage or a step-up DC-DC converter. The power may be chosen either from a DC battery or an external AC mains source. Then, a set of switches is used to open and close the current paths in order to control the motor speed and direction.

The periodic control is based on the duration of switch-on time, which determines the current flow through the motor windings and thus the motor speed. The higher the current flow, the greater the rotational speed. The switches are also capable of operating as choppers or saturated switches, to produce different types of drive signals based on the applications.

The speed control is based on the fact that the speed of the motor is dependent on the voltage applied to its winding. This voltage must be controlled in order to maintain a certain speed or torque depending on the type of application. Therefore, the chip is provided with a programmable voltage regulator (also called a regulator) that can adjust the current supply to the motor, and so to the speed control.

In conclusion, the MB86967PFV-G-BNDE1 IC chip has a great application field and working principle that can give a variety of motor control options to users. It is suitable for various types of motor control applications, and it is one of the most advanced digital controllers of motor motion.
