... Voice Coil Motors, high-frequency Class D audio amplifiers, and power supplies. For example, the HIP4081 can drive medium voltage brush motors, and two HIP4081s can be used to drive high perfor- mance stepper motors, since the short minimum “on-time” can provide fine micro-stepping capability. ...
