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.
