NXP USA Inc. MCZ33976EGR2

Description
The MC33976 is a single-packaged, Serial Peripheral Interface (SPI)-controlled, dual step motor gauge driver integrated circuit (IC). It consists of four dual output H-Bridge coil drivers and associated control logic. Each pair of H-Bridge drivers automatically controls the speed, direction, and magnitude of current through the two coils of a two-phase instrumentation step motor.
