Cordless vacuum cleaner

A reliable solution for vacuums and small motorized equipment

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.

Key features:

  • Ultra-low power MCU
  • High speed wake up time 4µs
  • Integrated 12-bit ADC with op amp and comparator
  • High accuracy cell balancer and monitor with customer programmable EEPROM


  • Vacuum cleaner
  • Small motor equipment
