Preliminary Information

33991

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.

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:

•

MMT-licensed two-phase stepper motor compatible

Minimal processor overhead required

Fully integrated pointer movement and position state machine with air

core movement emulation
