Motorola MC33033 Brushless DC Motor Controller Datasheet
The MC33033 is a high-performance, second-generation monolithic brushless DC motor controller designed for open-loop, three or four-phase motor control. It evolved from the MC33034 and MC33035 controllers but differs by lacking separate drive circuit supply and ground pins, a brake input, or a fault output signal. The device integrates a rotor position decoder, temperature-compensated reference, frequency programmable sawtooth oscillator, error amplifier, pulse width modulator comparator, and top and bottom drivers suitable for driving power MOSFETs.
