PMIC - Motor Drivers, Controllers - AH287-PG-B Application Field and Working Principle
Power management integrated circuits (PMICs) are critical components for assembling an efficient electrical system for a variety of settings. The AH287-PG-B IC is a highly efficient PMIC designed for motor drivers and controllers. In this article, we will explain the AH287-PG-B IC\'s practical application areas and its working principle.
Application Areas
The AH287-PG-B IC is primarily used as a motor driver or a motor controller. It can be applied to a variety of settings, including home appliance motors, industrial automation systems, and electric power tools. This IC is also suitable for fans, washing machines, refrigerators, air conditioners, electric toothbrushes, electric tools, electric wheelchairs, and other AC motor applications. In general, this IC provides great power efficiency and reliability for electric motor systems.
Working Principle
The AH287-PG-B IC integrates multiple functions in its compact design. It consists of a boost converter and two stages of integrated pulse-width-modulator (PWM) with adjustable frequency control. It has a sophisticated feature set and can work with both Hall-effect and three-phase sensors. Further, it also features a special over-current protection circuit that actively monitors current in an electric motor system.
The IC contains two independent channels, each capable of providing power to two motors. The IC also contains a logic signal comparator used to monitor Hall Effect signals from the motors, and an integrated timer circuit used to analyze signals from the motors.
In other words, when a motor needs more power, the IC sends a signal to the PWM circuit and the boost converter to provide more power. Meanwhile, the logic signal comparator monitors the Hall Effect signals from the motors and the timer circuit analyzes the signals from the motors. If the current in the motor system exceeds a certain limit, the over-current protection circuit will cut the motor power supply and alerts the user.
Conclusion
The AH287-PG-B IC is an efficient and reliable motor driver or motor controller. It can be applied to many different settings, including home appliance motors, industrial automation systems, and electric power tools. This IC is particularly useful as it integrates multiple functions and features a special over-current protection circuit.
