MCZ33991 Overview
Freescale Semiconductor Technical Data Gauge Driver Integrated Circuit This 33991 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...
