LS8297CT Datasheet Stepper Motor Controller

Manufacturer: LSI

Overview: LSI/CSI UL ® LS8297 LS8297CT (631) 271-0400 FAX (631) 271-0405 April 2009 LSI Computer Systems, Inc.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

: The LS8297 Stepper Motor Controller generates four phase drive signal outputs for controlling two phase Bipolar and four phase Unipolar motors.

The outputs are used to drive two H-bridges for the two motor windings in the Bipolar motor or the four driver transistors for the two center- tapped windings in the Unipolar motor.

The motor can be driven in full step mode either in normal drive (two-phase-on) or wave drive (one-phase-on) and half step mode.
