Overview
The NCV33035DWR2G is a high-performance, second-generation monolithic brushless DC motor controller produced by onsemi. This device is designed to implement a full-featured open-loop, three or four-phase motor control system. It includes all the active functions necessary for motor control, such as a rotor position decoder, a temperature-compensated reference capable of supplying sensor power, a frequency-programmable sawtooth oscillator, and high-current drivers to control external 3-phase MOSFET bridges. The controller also features various protective mechanisms, including undervoltage lockout, cycle-by-cycle current limiting, internal thermal shutdown, and a unique fault output that can be interfaced with microprocessor-controlled systems.
