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, direction and magnitude of current through the two coils of
a 2-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 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
4096 possible steady state pointer positions
