The MC33033DWG from onsemi is a second-generation, limited-feature monolithic brushless DC motor controller. It integrates essential functions for open-loop, three or four-phase motor control, including a rotor position decoder, a temperature-compensated reference, a programmable sawtooth oscillator, an error amplifier, and a pulse width modulator comparator.
This controller features three open-collector top drivers and three high-current totem-pole bottom drivers, suitable for driving power MOSFETs. It includes protective features such as undervoltage lockout, cycle-by-cycle current limiting with a selectable latched shutdown mode, and internal thermal shutdown. The MC33033DWG is designed for brushless motors with 60°/300° or 120°/240° electrical sensor phasings and can also control brush DC motors with an external H-bridge.
Key electrical specifications include an operating voltage range of 10 to 30V and a 6.25V reference voltage capable of supplying sensor power. The device is housed in a SOIC-20W package, suitable for surface mounting.
