Brushless DC
Motor Controller
The MC33033 is a high performance second generation, limited feature,
monolithic brushless dc motor controller which has evolved from Motorolas
full featured MC33034 and MC33035 controllers. It contains all of the active
functions required for the implementation of open loop, three or four phase
motor control. The device consists of a rotor position decoder for proper
commutation sequencing, temperature compensated reference capable of
supplying sensor power, frequency programmable sawtooth oscillator, fully
accessible error amplifier, pulse width modulator comparator, three open
collector top drivers, and three high current totem pole bottom drivers ideally
suited for driving power MOSFETs. Unlike its predessors, it does not feature
separate drive circuit supply and ground pins, brake input, or fault output
signal.
Included in the MC33033 are protective features consisting of
undervoltage lockout, cycle–by–cycle current limiting with a selectable time
delayed latched shutdown mode, and internal thermal shutdown.
Typical motor control functions include open loop speed, forward or
reverse direction, and run enable.The MC33033 is designed to operate
brushless motors with electrical sensor phasings of 60°/300° or 120°/240°,
and can also efficiently control brush dc motors.
