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 through the two coils of a two-phase instrumentation stepper motor, similar to an MMT licensed AFIC 6405.
This device is ideal for use in automotive instrumentation systems requiring distributed and flexible stepper motor gauge driving.
The device also eases the transition to ste...
