Introduction to Class PMIC - Motor Drivers, Controllers

Power management integrated circuits (PMICs) are integrated circuits that control the behavior and state of electronic devices. This involves regulating the current and voltage supplied to the device by the system power supply. The power supply regulates the output voltage depending on input voltage. PMICs are used for many applications, such as motor drives, and controllers.Motor drivers and Controllers are digital devices that can be used to regulate the output voltage from the power supply. They provide control over the speed, acceleration, and power of a motor, enabling it to move to specific locations and operate at different speeds. In addition, they can be used to monitor the performance of the motor and provide safety protections in case of any potential problems.
