Power Management IC (PMIC) systems are emerging in many applications. One such system is BU24036MWV-E2, which is a motor driver, controller and voltage regulator. This article focuses on the application field and working principle of the BU24036MWV-E2 integrated circuit.

Application Field

The BU24036MWV-E2 is designed to operate as a motor driver, controller and voltage regulator for automotive applications. It can operate at a wide range of supply voltages up to 18V. As a motor driver, it can be used to control driving and braking of motors with peak currents in excess of 10A and frequencies up to 200kHz. As a controller, it can be used to regulate speed, current and power of motors to deliver maximum efficiency and prevent dangerous overloads. As a voltage regulator, it can be used to deliver constant voltage to the motor, aiding its performance and improving power efficiency. It is also equipped with four chopper-controlled drivers, providing multiple levels of current control for various applications.

Working Principle

The BU24036MWV-E2 IC is a fully-integrated circuit, meaning all its components are included in the same package. This makes it very easy to use, but also means its working principle is more complex than other systems. To understand how it works, it helps to look at the individual components that make up the IC.

The main component of the BU24036MWV-E2 is a high-speed buck converter. This converts the input voltage into a regulated output voltage which can be used to drive the motors. It is connected to two output channels, each of which can be used to control two motors. Each output channel consists of two low-side power MOSFETs and two high-side power MOSFETs, which are used to accurately control the motor driver. This part of the circuit is also connected to a current sense resistor, which provides feedback to the motor driver and helps to detect motor overloads.

The next component of the BU24036MWV-E2 is a voltage regulator. This is used to ensure that the output voltage is regulated and within the appropriate range for the application. This is important because it helps to reduce power losses and also improve motor performance. The voltage regulator is connected to two pulse-width modulation (PWM) circuits, which are used to control the output of the motor driver. These circuits generate the signals needed to switch between high and low power output levels, allowing the motors to be accurately controlled.

Finally, the BU24036MWV-E2 is equipped with four chopper-controlled drivers. These are used to control the speed of the motors by controlling the current output. The chopper-controlled drivers are connected to a power control circuit, which adjusts the output voltage and current requirements depending on the application. This helps to ensure maximum efficiency, and also prevents motor overloads.

In summary, the BU24036MWV-E2 motor driver, controller and voltage regulator system is an integrated circuit designed for automotive applications. It has a wide range of supply voltages and is capable of controlling peak currents of up to 10A and frequencies of up to 200kHz. Its main component is a high-speed buck converter, which is connected to two output channels and a current sense resistor. It also has a voltage regulator and two PWM circuits, as well as four chopper-controlled drivers and a power control circuit. All these components work together to provide precise motor control, efficient power management and maximum motor performance.
