NCP81071AZR2G application field and working principle

NCP81071AZR2G gate drive power management integrated circuit (PMIC) is used for motor control applications such as air conditioning systems, fans, and blowers. It integrates a variety of features designed to make the application simpler, more reliable, and more efficient.

The NCP81071AZR2G PMIC consists of three major components: a high-side driver, a low-side driver, and a logic controller. The high-side driver is a high-voltage power MOSFET switch driven by a PWM waveform that allows for fast switching. It is designed for use in motor control applications and has a maximum operating power of 500 watts. The low-side driver is a low-voltage power MOSFET switch driven by a separate PWM waveform. It is designed to be used with the high-side driver and has a maximum operating power of 100 watts.

The third component of the power management system is the logic controller. This component manages the power distribution, monitors the current and voltage applied to the component, and communicates with the external controller. It is responsible for providing the appropriate voltage and current to the component, as well as ensuring that the component remains in regulation and within a specified temperature range.

The working of the NCP81071AZR2G PMIC is quite simple. When the external controller sends out the PWM waveform, the logic controller processes the information to determine the required voltage and current for the component. The voltage is then applied to the high-side driver and low-side driver, which then switch on and off to regulate the power. The system is designed to provide a safe and efficient operation of a motor and its other components, while protecting it from overvoltage and overcurrent conditions.

The NCP81071AZR2G PMIC can be used in a variety of applications, such as motor control systems, automotive systems, consumer electronics, and industrial systems. It is suitable for full-bridge and half-bridge applications, providing excellent overvoltage, overcurrent, and temperature protection. The NCP81071AZR2G is a highly integrated, low-cost PMIC, providing solutions for a wide range of applications.
