Experimental selection of R
T
and C
T
allow the designer to se-
lect a small amount of winding current overshoot, as shown
above. Although the overshoot may exceed the continuous
rated current of the winding and the drive transistors, the dura-
tion can be well controlled. Average power dissipation for the
driver and motor must be considered when designing sys-
tems with intentional overshoot, and must stay within conser-
vative limits for short duty cycles.
In this application, the
A and
B outputs of the UC3517 are
connected to the current program inputs of the UC3717. This
allows the UC3517 inhibit signal to inhibit the UC3717, and
also allows half-step operation of the UC3717. Peak motor
winding current will be limited to approximately .42V/R1 by
chopping.
