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.
