Typical Application Description The INT100 half-bridge driver IC provides gate drive for external low-side and high-side MOSFET switches. The INT100 provides a simple, cost-effective interface between low-voltage control logic and high-voltage loads. The INT100 is designed to be used with rectified 110 V or 220 V supplies. Both highside and low-side switches can be controlled independently from ground-referenced 5 V logic inputs. Built-in protection logic prevents both switches from turning on at the same time and shorting the high voltage supply. Pulsed internal level shifting saves power and provides enhanced noise immunity. The circuit is powered from a ...
