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.
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.

Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect
device reliability.
1. The input common mode voltage or input signal voltage should not be allowed to go negative by more than 0.3 V.
2. The compliance voltage must not exceed the range of − 0.3 to Vref.
3. NCV33033: Tlow = −40°C, Thigh = 125°C. Guaranteed by design. NCV prefix is for automotive and other applications requiring site and change
control.
