MOTOROLA ANALOG IC DEVICE DATA
Brush Motor Control
Though the MC33035 was designed to control brushless
DC motors, it may also be used to control DC brush type
motors. Figure 46 shows an application of the MC33035
driving a MOSFET H–bridge affording minimal parts count to
operate a brush–type motor. Key to the operation is the input
sensor code [100] which produces a top–left (Q
1
) and a
bottom–right (Q
3
) drive when the controller’s forward/reverse
pin is at logic [1]; top–right (Q
4
), bottom–left (Q
2
) drive is
realized when the Forward/Reverse pin is at logic [0]. This
code supports the requirements necessary for H–bridge
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. Cycle–by–cycle current
limiting of the motor current is accomplished by sensing the
voltage (100 mV) across the R
S
resistor to ground of the
H–bridge motor current. The over current sense circuit makes
it possible to reverse the direction of the motor, using the
normal forward/reverse switch, on the fly and not have to
completely stop before reversing.
LAYOUT CONSIDERATIONS
Do not attempt to construct any of the brushless
motor control circuits on wire–wrap or plug–in prototype
boards.
High frequency printed circuit layout techniques are
imperative to prevent pulse jitter. This is usually caused by
excessive noise pick–up 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

and the error
amp 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.
