1 / 41 page Document Number: MC33976 Rev 4.0, 1/2007 Freescale Semiconductor Advance Information * This document contains certain information on a new product. Specifications and information herein are subject to change without notice. © Freescale Semiconductor, Inc., 2007. All rights reserved. Dual Gauge Driver with Configurable Response Time The 33976 is a single-packaged, Serial Peripheral Interface (SPI) controlled, dual step motor gauge driver integrated circuit (IC). This monolithic IC consists of four dual output H-Bridge coil drivers and the associated control logic. Each pair of H-Bridge drivers is used to automatically control the speed, direction, and magnitude of current through the two coils of a two-phase instrumentation step motor, similar to an MMT-licensed AFIC 6405 or Switec MS-X15.xxx motor. The 33976 is ideal for use in automotive instrumentation systems requiring distributed and flexible step motor gauge driving. The device also eases the transition to step motors from air core motors by emulating the air core pointer movement with little additional processor bandwidth utilization.
