MOTOROLA ANALOG IC DEVICE DATA
Figure 38 shows a three phase, three step, half wave motor
controller. This configuration is ideally suited for automotive
and other low voltage applications since there is only one
power switch voltage drop in series with a given stator
winding. Current flow is unidirectional or half wave because
only one end of each winding is switched. Continuous braking
with the typical half wave arrangement presents a motor
overheating problem since stator current is limited only by the
winding resistance. This is due to the lack of upper power
switch transistors, as in the full wave circuit, used to
disconnect the windings from the supply voltage V
M
. A unique
solution is to provide braking until the motor stops and then
turn off the bottom drives. This can be accomplished by using
the Fault Output in conjunction with the Output Enable as an
over current timer. Components R
DLY
and C
DLY
are selected
to give the motor sufficient time to stop before latching the
Output Enable and the top drive AND gates low. When
enabling the motor, the brake switch is closed and the PNP
transistor (along with resistors R
1
and R
DLY
) are used to reset
the latch by discharging C
DLY
. The stator flyback voltage is
clamped by a single zener and three diodes.
