I just took on a project for a dedicated machine logic controller and I had
to include a driver for a 90V 1.75A PMDC Motor with current limiting per the
client's request. This is great, but I haven't done much with motors since
SUNY more than 20 years ago. While playing around with discrete switching
transistors, I realized that Motorola used to make all sorts of motor
control chips. Aside from not seeing any at Motorola.com, my initial search
showed that single chip driver/controllers seem to max out at about 46
volts.
So I believe that to simplify my desugn I should be looking for drivers for
controlling IGBT's or MOSFET's. I think power MOSFET's are the right choice
for the voltage and size of the motor anyway.....

Could anyone help narrow my search or correct my thinking on this?

TIA,
Chris
