Gauge Driver Integrated Circuit

33991

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.

GAUGE DRIVER INTEGRATED CIRCUIT

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 stepper motors from air core

motors by emulating the air core pointer movement with little

additional processor bandwidth utilization.

The device has many attractive features including:
