Motorola 33991
33991 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 two-phase instrumentation stepper motor, similar to an MMT licensed AFIC 6405.| Part No. | 33991 |
