詳細說明

The MC33035DW is a highly integrated Brushless DC motor controller designed for use in applications such as fans, blowers, and pumps. It features a three-phase bridge driver with on-chip commutation logic, a speed control input, and thermal shutdown protection. The controller operates from a 12V power supply and can drive motors up to 60V. The MC33035DW's commutation logic eliminates the need for Hall sensors, simplifying motor control circuitry and reducing overall system cost. It also provides smooth and precise motor speed control through the speed control input, allowing for efficient operation across a wide range of speeds. Other key features of the MC33035DW include overcurrent and short-circuit protection, thermal shutdown, and a power-saving sleep mode. The device is housed in a 20-pin SOIC package, making it suitable for space-constrained applications.
