The development of proprietary cir-
cuits has minimized ripple current,
while maintaining a 20 KHz chop-
ping rate. This prevents additional
motor heating that is common with
drivers requiring higher chopping
rates. Now low inductance stepper
motors can be used to improve
high speed performance and peak
system efficiency.

The IM2000S is a high perfor-
mance microstepping controller
that incorporates a sine/cosine
signal generator, anti-resonance
circuitry, PWM current control
and much more in one monolithic
IC. The IM2000S combines hard-
ware intense functions together
with innovative features to provide
designers with a powerful yet simple
solution for their high volume OEM
products.
