Advance Information  
Dual Gauge Driver with  
Configurable Response Time  
33976  
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.  
CONFIGURABLE DUAL GAUGE DRIVER  
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.
