MC33033, NCV33033

Brushless DC

Motor Controller

The MC33033 is a high performance second generation, limited

feature, monolithic brushless dc motor controller which has evolved

from ON Semiconductor’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

predecessors, it does not feature separate drive circuit supply and

ground pins, brake input, or fault output signal.

PDIP−20

P SUFFIX

CASE 738

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.

SO−20L

DW SUFFIX

CASE 751D

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.
