DESCRIPTION
For example, the HIP4081 can drive medium voltage brush motors, and two HIP4081s can be used to drive high performance stepper motors, since the short minimum “on-time” can provide fine micro-stepping capability. Short propagation delays of approximately 55ns maximizes control loop crossover frequencies and dead-times which can be adjusted to near zero to minimize distortion, resulting in rapid, precise control of the driven load. A similar part, the HIP4080, includes an on-chip input comparator to create a PWM signal from an external triangle wave and to facilitate “hysteresis mode” switching. See Application Note AN9325 for HIP4081, Intersil AnswerFAX, (407) 724-7800, document #99325. Intersil web home page: Similar part HIP4081A includes undervoltage circuitry which does not require the circuitry shown in Figure 30 of this data sheet.
