PC33991DH Datasheet | Motorola Semiconductor

Freescale Semiconductor, Inc. MOTOROLA SEMICONDUCTOR TECHNICAL DATA Document order number: MC33991/D Rev. 0, 10/2002 Preliminary Information Gauge Driver Integrated Circuit The 33991device is a single packaged, Serial Peripheral Interface (SPI) controlled, dual stepper 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 2-phase instrumentation stepper motor, similar to an MMT licensed AFIC 6405.
