Introduction

This article takes LM628N-6/NOPB, which belongs to PMIC (Power Management Integrated Circuits) as an example. It is part of Motor Drivers, Controllers (MDC). This article will explain its applications and working principle.

What is the LM628N-6/NOPB?

LM628N-6/NOPB is a motor driver in PMIC. It is a PWM (Pulse Width Modulated) motor driver, designed for power motor applications. Itcontrols and drives DC motor, brushless motor, stepped motor, and so on. It is designed to provide high power, accuracy, and reliability.

Working Principle and Applications

LM628N-6/NOPB is based on Pulse Width Modulation (PWM) technology. It generates pulse train, switches the output and controls the speed of the motor. The speed of the motor is determined by the frequency of the pulses. The width of the pulses will control the power. The length and frequency of the pulse train are adjustable. So the user can easily control the speed of the motor.

This module has wide applications. It can be used as DC motor driver, brushless motor driver or as a stepped motor driver. It can be also used in robotic driving system, toy driving system, and other motor control applications.

LM628N-6/NOPB is designed for low noise and low power consumption. It can operate at low voltage and high current. It is capable of performing the functions of multiple Hall elements, so it greatly simplifies the wiring process. It can support up to 5.5V voltage, and can draw up to 2A of current.

One of the important features of the LM628N-6/NOPB is its on-chip closed loop control. This helps to ensure the accuracy and stability of the motor performance. It also has an over-temperature protection circuit. This can prevent the motor from overheating and damaging itself.

Conclusion

The LM628N-6/NOPB is an integrated motor driver from PMIC. It is based on Pulse Width Modulation (PWM) technology. It can generate pulse train, switch the output and control the speed of the motor accurately. It has a wide range of applications, such as DC motor driving, brushless motor driving, stepped motor driving, robotic driving and toy driving. It is highly efficient and low power consuming. It also has an on-chip closed loop control, which ensures accuracy and stability of the motor performance.
