MC33033P

BRUSHLESS DC MOTOR CONTROLLER

 

 

The MC33033 is a high performance second generation, limited feature,

monolithic brushless dc motor controller which has evolved from Motorola′s

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.
