Cordless Vacuum Cleaner
Solutions for BLDC motor applications have been increasing rapidly because of the demand for products that are smaller in size and provide high efficiency. The core of a BLDC motor design is a robust and reliable motor control circuit and a versatile MCU for a safe control algorithm. A vacuum cleaner is one of the applications that uses a BLDC motor, but can be used in other similar applications. Key building blocks of a motor control circuit include a MOSFET driver, versatile MCU, voltage regulators, a cell balancer and the battery charger.
