Technical Data
Dual Gauge Driver with
Configurable Response Time
The 33976 is a single-packaged, Serial Peripheral Interface (SPI)
controlled, dual step 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 step motor,
similar to an MMT-licensed AFIC 6405 or Switec MS-X15.xxx motor.
The 33976 is ideal for use in automotive instrumentation systems
requiring distributed and flexible step motor gauge driving. The
device also eases the transition to step motors from air core motors
by emulating the air core pointer movement with little additional
processor bandwidth utilization.
