Power Integrations Inc. INT100S
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.| Part No. | INT100S |

DESCRIPTION
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 nominal 15 V supply to provide adequate gate drive for external N-channel MOSFETs. A floating high-side supply is derived from the low-voltage rail by using a simple bootstrap technique.APPLICATIONS
for the INT100 include motor drives, electronic ballasts, and uninterruptible power supplies. Multiple devices can also be used to implement full-bridge and multi-phase configurations. The INT100 is available in a 16-pin plastic SOIC package.
