PMIC (Power Management Integrated Circuits) encompasses a variety of applications, from controlling power distribution in electronic devices to providing protection against electrical malfunctions. In the field of motor control, one of the most popular devices is the LV8747TA-NH integrated circuit. This IC is a dedicated motor driver and controller, used to regulate the speed, position, and direction of a variety of stepper motors and spindle motors.

When designed into an appropriately configured circuit board, the LV8747TA-NH is capable of controlling up to four stepper motors or two spindle motors simultaneously. It supports most available control methods, including step/direction, analog voltage, and pulse width modulation (PWM). Additionally, the IC contains two analog comparators for monitoring the speed of stepper motors, further enhancing its flexibility. The maximum output current is rated up to 2A per phase and 4.5A peak.

The LV8747TA-NH integrates an input reference voltage which allows an adjustable current limit by the circuit itself, simplifying the development process and reducing component count. The IC has built-in protection against over current, over voltage, under voltage, and over temperature, making it an extremely robust and reliable part suitable for even the most potentially hazardous industrial and commercial applications.

On the functional side, the LV8747TA-NH provides a total of ten logic inputs, allowing it to easily interface with any external host microcontroller. The logic inputs allow for a variety of functions, such as accelerating and decelerating the motor, braking, directing it clockwise and counterclockwise, and setting the position. Each of these functions can be controlled via the step/direction input lines, the analog voltage input, or the PWM input.

The LV8747TA-NH also contains two half-bridge power stages controlling the two windings of a stepper motor, or the two sets of windings of a spindle motor. Each of these power stages is crossed-coupled with a pair of IGBTs, making the IC both robust and efficient. Furthermore, the IC is designed to minimize electromagnetic interference (EMI) while operating, thus reducing the need for additional decoupling capacitors.

In summary, the LV8747TA-NH integrated circuit is an extremely versatile and reliable motor driver and controller, suitable for a variety of applications, from controlling small- to medium-sized stepper and spindle motors. Its integrated protections and EMI mitigation make it suitable even for the most hazardous applications, while its wide range of control methods and configurable inputs simplify development and ensure compatibility across various systems.
