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.  
SEMICONDUCTOR  
TECHNICAL DATA  
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.
