Power management integrated circuit (PMIC) device like the LV8136V-MPB-H provide a vital functionality to everyday electronic products. In this article, we will explore the application field and working principle of the LV8136V-MPB-H - a motor driver, controller and regulator PMIC.

Application fields

The LV8136V-MPB-H is a versatile PMIC suitable for a wide range of applications in terms of controlling power and interfacing motors. Primarily, the LV8136V-MPB-H is designed to be used in high-power applications as it can provide power up to 30A peak per channel. Common applications for this kind of PMIC include motor drivers in electric vehicles, industrial robot operations, high power motor controllers, and lighting solutions. It is also an ideal choice for motor control in home appliances and white goods.

Features

The LV8136V-MPB-H is packed with a wide range of features. It’s a 3-channel motor controller and regulator PMIC that has independent standby duty control for each of its channels. It’s built with a dual-channel embedded regulator and a single-channel embedded regulator for delivering adjustable output voltage for motors. In addition, its low on-resistance FETs can provide a maximum output current of 30A peak. It also has a slew rate control and a separate PWM signal control for each motor. All these features make it extremely versatile and customizable for power management applications.

Working Principle

The LV8136V-MPB-H makes use of an integrated circuit (IC) containing a variety of components for controlling power and interfacing with motors. It has two-phase three-level pulse width modulation (PWM) that drives low resistance MOSFETs. The controller receives a PWM signal from the host machine, amplifies it, and then outputs a rectangular wave. This wave is then used by the FETs to drive the motor. This helps to reduce the power consumption and minimize the heat generation.

It also has an adaptive on-time control feature which helps to reduce the current ripple. It works by calculating the on-time based on the input PWM signal, thus reducing the current ripple in operation. In addition, it is also equipped with slew rate control circuit which prevents sudden changes in motor rotation and provides a smoother operation.

The LV8136V-MPB-H also features a built-in stand-by duty control for each channel via feedback signals from thehost machine. This helps to reduce the power consumption in idle state and optimise the performance of the motor.

Conclusion

The LV8136V-MPB-H is a high performance PMIC designed for motor control and regulation applications.It is packed with features that enable it to deliver an adjustable output voltage with a maximum output current of 30A peak and provide a smoother operation with reduced current ripple. Its adaptive on-time control and slew rate control circuits help to optimise the performance and reduce power consumption. Additionally, its stand-by duty control allows it to reduce power consumption during idle periods. This makes the LV8136V-MPB-H an ideal choice for power management in electric vehicles, industrial robots and home appliances.
