PC33991DH Gauge Driver Integrated Circuit

H-Bridge Output. This is the output pin of a half bridge, designed to source or sink current. The H-Bridge pins linearly drive the sine and cosine coils of two separate stepper motors to provide four-quadrant operation. H-Bridge Output. This is the output pin of a half bridge, designed to source or .

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, directi.
