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.

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.

CASE 738

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.

• 10 to 30 V Operation

• Undervoltage Lockout

• 6.25 V Reference Capable of Supplying Sensor Power

• Fully Accessible Error Amplifier for Closed Loop Servo Applications

• High Current Drivers Can Control External 3–Phase MOSFET Bridge

• Cycle–By–Cycle Current Limiting
