Data Sheet

This solution can drive until 3 Amps In DC operation
and until 3.5 Amps of a repetitive peak current.
On Fig 8 it is shown the driving of a two phase bipolar
stepper motor ; the needed signals to drive the in-
puts of the L298 are generated, in this example,
from the IC L297.
Fig 9 shows an example of P.C.B. designed for the
application of Fig 8.
Fig 10 shows a second two phase bipolar stepper
motor control circuit where the current is controlled
by the I.C. L6506.
Figure 8 : Two Phase Bipolar Stepper Motor Circuit.
This circuit drives bipolar stepper motors with winding currents up to 2 A. The diodes are fast 2 A types.
