www.DataSheet4U.com Freescale Semiconductor Advance Information Document Number: MC33970 Rev. 3.0, 1/2007 Dual Gauge Driver Integrated Circuit with Improved Damping Algorithms This 33970 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. The 33970 is ideal for use in automotive instrumentation systems requiring distributed and flexible step motor gauge driving.
