Brush Motor Control
Though the MC33033 was designed to control brushless dc
motors, it may also be used to control dc brushtype motors.
Figure 44 shows an application of the MC33033 driving a
Hbridge affording minimal parts count to operate a
brushtype motor. Key to the operation is the input sensor
code [100] which produces a topleft (Q
1
) and a bottomright
(Q
3
) drive when the controller’s Forward/Reverse pin is at
logic [1]; topright (Q
4
), bottomleft (Q
2
) drive is realized
when the Forward/Reverse pin is at logic [0]. This code
supports the requirements necessary for Hbridge drive
accomplishing both direction and speed control.
The controller functions in a normal manner with a pulse
width modulated frequency of approximately 25 kHz.
Motor speed is controlled by adjusting the voltage presented
to the noninverting input of the Error Amplifier establishing
the PWM
′
s slice or reference level. Cyclebycycle current
limiting of the motor current is accomplished by sensing the
voltage (100 mV threshold) across the R
S
resistor to ground
of the Hbridge motor current. The over current sense circuit
makes it possible to reverse the direction of the motor, on the
fly, using the normal Forward/Reverse switch, and not have
to completely stop before reversing.
LAYOUT CONSIDERATIONS
Do not attempt to construct any of the motor control
circuits on wirewrap or plugin prototype boards.
High
frequency printed circuit layout techniques are imperative to
prevent pulse jitter. This is usually caused by excessive noise
pickup imposed on the current sense or error amp inputs.
The printed circuit layout should contain a ground plane
with low current signal and high drive and output buffer
grounds returning on separate paths back to the power
supply input filter capacitor V

ref
and error amplifier noninverting input may be required
depending upon circuit layout. This provides a low
impedance path for filtering any high frequency noise. All
high current loops should be kept as short as possible using
heavy copper runs to minimize radiated EMI.
