C i r c u i t O p e r a t i o n

The IB462H is a bipolar chopping stepper motor drive. It receives step clock,
direction and mode signals from the system controller to generate constant
phase currents which are adjustable in magnitude.

The principal function blocks are: a translator which generates the motor
phase sequences, a dual PWM chopper circuit which regulates the current in
