The HS-4080ARH is a monolithic, high frequency, medium voltage Full Bridge N-Channel FET Driver IC. The device includes a TTL-level input comparator, which can be used to facilitate the "hysteresis" and PWM modes of operation. Its HEN (high enable) lead can force current to freewheel in the bottom two external power MOSFETs, maintaining the upper power MOSFETs off. The HS-4080ARH is well suited for use in distributed DC power supplies and DC to DC converters, since it can switch at high frequencies. These devices can also drive medium voltage motors, and two HS-4080ARHs can be used to drive high performance stepper motors, since the short minimum "on-time" can provide fine micro-stepping capability. Short propagation delays maximize control loop crossover frequencies and dead-times, which can be adjusted to near zero to minimize distortion, resulting in precise control of the driven load.
