Key Features

and system diagnostics are provided via a serial interface under the direction of an external microcontroller. The large-scale integration and use of advanced DABiC™ (digital/analog-BiCMOS) merged technologies results in minimum power dissipation, minimum operating voltage requirements, and minimum external components. The spindle drive function incorporates a three-phase MOS power driver and a back-EMF sensing motor commutation scheme. Internal logic and analog circuitry provide complete start-.
