INT72W4M256M8M-A03GZU - Brand New STEC IC Chips
-
Description
The INT100 half-bridge driver IC provides gate drive for external low-side and high-side MOSFET switches. It is designed to be used with rectified 110 V or 220 V supplies. The INT100 can be controlled independently from ground-referenced 5 V logic inputs. It has built-in protection logic to prevent both switches from turning on at the same time and shorting the high voltage supply. 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.
