Hi

I am building 2 H bridges to drive a bipolar stepper motor controlled by a
PIC . I would like to apply 50 to 80 volts. I understand that there are H
bridge drivers for the mosfets like HIP4081A. But find them a bit costly
almost $10USD a piece and I need 2 pieces. Is there an alternative to make a
charge pump circuit to solve the problem of switching on the upper channel
FETs?

thanks

Regards,
Richard
